Just got 5920 laptop, but on initial startup, I only see F2 for setup, I tried pressing F10 or Alt-F10, but the restore menu does not come up.

I saw on another post ( that you have (
I saw wondering if I should use that file for 5920 or is that MBR fix laptop model specific?

    There are still 3 partitions there, 1 hidden 9gb, , then it's c: with ~180gb running Vista Home Premium OS, then another hidden 4gb partition after that.

    The laptop is running OEM Vista Premium, but I did not get any disk when I bought it from the guy. Only the international warranty was given to me.

  • mding Feb 17, 2008

    I was able to (somehow) got the auto-restore to work once (using the 9gb), but it's stuck at installing eRecovery Step 7 of 8. When I reboot, it keeps looping into Alt-F10 restore screen without booting properly.

    I ended up install another Vista on top to get around it. But now, I'm trying to restore the Acer 9gb image back, but I can't get the Alt-F10 to work again.

    I'm still trying to run the 'mbrwrwin.exe install rtmbr.bin'

    I also noticed in rytools folder, there are also rtmbr2.bin and vistaboot.bin. Which .bin should I use?

  • mding Feb 17, 2008

    I was able to run 'mbrwbwin.exe install rtmbr.bin' (with program\accessories\command prompt (run as admin)), reboot, enable D2D from BIOS, reboot but now I get a blinking cursor on upper left corner.

    It's a 9GB along with a 177GB partition, the 3.2 GB is after the 177GB and I don't think it does anything.

    What do I do with blinking cursor now?

    I dont speek english very well.

    But i think that if you push ALT+F10, you have to weit a fieu minutes.

    You think that Windows Vista is reload, but after somme minutes, you can see the menu of restore.

    Thik you

I've had this problem before with exactly the same computer. What you have to do is after you see the screen with F2 to enter BIOS, you have to hit F8 NOT F10 and then it takes you to another screen. At this screen you need to hit "Startup Repair". If your hard drive won't let you go past that point and says to choose another option than your hard drive is corrupted, but if it does you will to go to a Windows Safe-mode looking screen that allows you to choose your options for repair 2 of which are system restore and complete system restore. Hope this helps!

3.2GB partition is XPe (win XP express) partition. Do u know Arcade?? Turn off your laptop, then press Arcade button ( i didn't mean power button)- the button under Empower button- and now, do u see Arcade work???
@misterwasp: aspire 5920 have OEM partition only(9GB). U don't need original restore disc. If Alt+F10 wont work, u can get back all driver only. Download and install eRecovery, choose reinstall driver. eRecovery 'll get back ur driver from OEM partition. Then choose right driver to install.
P.S: sry about my English :P. There 's a lot of English's mistake.

Most likely the restore partition has been erased. If you are in the USA, by law, used laptops must be sold without an operating system. Sometimes with big bulk second hand buys, the reseller erases the wrong partition (recovery must be done from a separate small partition). Does the laptop have an operating system? Windows 98, 2K, \XP or Vista? If so, you can open disk management in administrative tools and look to see if there is a recovery partition. It will be between 8 to 120mb or so. Let me know and we can take this a step farther

    OK, thanks for finding all the utilities and providing such good details.

    First, let me brief you on how things appear, right now:

    Since you have been running this system, and booting several times, the internal windows "repair" and "restore" function would be useless. Those only fix problems with the existing OS -or restore the same OS from the last known good boot configuration. So the MS F6/F8 options are a waste of time.

    Now, as for the OEM Acer "restore", that must be done when booted from a separate OS container from the target directory (your 180gb C drive). To restore THAT c drive, you must start on some other partition or media. Normally, this is built in, and the restore partition, which has a small DOS-like OS, boots when you invoke Alt-F10. The fact that this option does not exist anymore is almost certain to be due to someone replacing/upgrading the previous OS with a boot-able Windows CD installer, then leaving the old restore partition without upgrading that too.. For example, if the laptop originally came with XP, and the previous owner upgraded to Vista, but failed to choose a backup (make an auto restore). Now, there is a possibility you can still restore the previous OS, but at best, you can only restore whatever OS was installed previously (which may be some XP version).

    Now, for the current situation. Unfortunately, both the 9gb partition and the 4gb partition are big enough to be a restore partition. So this is not quite clear yet. Please be patient, I need to send you back to do the same thing again, and be VERY sure that the 4gb partition is not 4mb instead! It is unusual to have TWO hidden partitions so large, unless one of them is Linux (which must "hide" from Microsoft OS, since MS is a predatory OS). If the partition you think is 4 GIGAbytes, is actually 4 MEGAbytes, then this makes better sense, because it is most likely a standard NTFS directory partition (they are usually 4-8mb). MS usually makes this 4-8mb partition on a new install. So if you find that one is only 4mb, then we have ONLY one possible restore partition (the 9gb). We have to be absolutely sure. So go look and get back to me. Remember, if the utility lists sizes in "GB" then your data is presumably correct. However, if it lists sizes in MB, then 4gb would be 4,000mb. But the much smaller container, of only 4mb would be listed as 4,000kb or 4,000,000bytes. If this was the case, then we can assume the 9gb is the ONLY possible restore partition. So please go look again and verify this.

    Dana Stienheimer Feb 17, 2008

    Aha! Now I see what has happened here. You were playing around with the restore partition, trying to run things manually, from C drive instead of boot time? You absolutely cannot do that! You must be running on a different partition, in order to restore the main/active partition. If that is what you have done, the rest of this reply applies.

    You cannot "get there from here", and just trying that once, will corrupt the entire process. This is because the executable you are trying to run is a MBR restore. That is "master boot record", the "street map" your computer uses to find the operating system's location on the hard drive. This is really critical stuff. And you were trying to "restore" an operating system that has already been replaced! So the old master boot record (what you did install) is now pointing to the old location of the OS before it was replaced! (and it no longer exists there) If the 4gb container (you never answered me!) was actually 4gb instead of 4mb, then the original setup was probably something like this:

    Windows XP on 4gb partition HD0/0 (c drive)
    Windows Vista on 9gb partition HD0/1 (d drive)
    and a huge 128gb "black hole hard drive" (e drive) for movies/MP3s, etc.

    This is typical dual-boot system most experts will use on a laptop like yours since many laptop features do not work yet on Vista, so they want to be able to fall back to XP for missing functions/features and hardware compatibility. Thus when the laptop was started, boot.ini threw up a "menu list" with XP and Vista offered as a choice (up arrow/down arrow and/or enter). Now, somehow, you have the OS installed on that biggest container (128gb) now. That is "upside down" from most logical setups, since you want the OS on the smaller drive, since accessing a smaller directory makes the OS run MUCH faster than when it resides in a large partition. Anyway, I am 99% sure of this, your MBR is now unrecoverable, and therefore, when the restore partition restarts, it never finishes, because the OS is not where it is supposed to be (where it was originally, on either 9gb or the 4gb drive). What does all this mean? Unless you have a REALLY good geek there near you, who has an external USB laptop hard drive container, you are screwed. You will never fix this! Believe me, the restore is never going to finish (or succeed), whatever remnant OS you are able to load now is incomplete, missing lots of functionality, and you will always be missing the use of some hidden partitions! I do not see any way out of this, except to get a XP CD installer (which is where you need to start, load it on 4gb). Get Vista loaded later as a second option, on 9gb, and keep the 128 for storing all documents and multimedia. All three drives should be formatted (erased) with the XP CD before loading XP. The latter is important, since the restore is invalid, and will otherwise always be booting (but never completing) if the primary OS is disrupted. XP CD installers are VERY cheap now, since (idiots) consider XP to be "outdated" or Vista to be an improvement. You will see what I mean, when Vista is incapable of using many laptop features you have, and worse, many features disappear after suspend/hibernate (a common unresolved problem with laptop Vista installs, requiring a reboot after sleep to regain functions). If this were not true, MS would not have "backtracked" and released a new 64-bit XP after releasing Vista! Consumers demanded laptops work. So obviously, if you have a dual core or some other 64 bit processor, get the appropriate 64bit XP CD. You can worry about Vista after you get the laptop running properly, without those invalid ghost partitions.

My Acer Aspire 5335 turns on but then just goes to a black screen with a flashing white "underscore". Any ideas what could be wrong?

It sounds as though you have a corrupt boot sector, you may be able to access a system restore but THIS WILL WIPE YOUR DATA. Usually accessed through clicking alt and F10 during the initial boot sequence. Hope this helps

How to reformat acer aspire one netbook

The most hassle-free way to format your Acer Aspire One is through the built-in eRecovery software. This application exists within a hidden partition on your computer's hard drive along with a pristine copy of Windows. When you invoke this program, it will clear most of your hard drive and install a fresh copy of Windows to it. You can effectively reset your computer to the condition it was in when you first turned it on.

1. Connect the Aspire One's power adapter to the computer, and plug it into the wall.

2. Turn the computer off by clicking "Start" and then "Shut down."

3. Press the Power button. After 20 seconds, press and hold the "Alt" key and then tap "F10" repeatedly as your computer boots up.

4. Release the "Alt" key when the "Starting Acer eRecovery" screen appears.

5. Press the "1" key to select the "Restore system to factory default" option.

6. Enter your eRecovery password in the space provided, and press "Enter."

7. Read the Acer eRecovery terms and conditions, and then click the "Yes" button to signify that you understand and agree.

8. Click "Next" to initiate the formatting process.

9. Follow the step-by-step setup process for Windows that begins after the unit restarts.

I hope you find it very helpful.

I have installed Windows 7 to my Acer Aspire One AOD255 but i want to revert it back to Windows XP and I no longer have the Windows.old folder. How can i downgrade it back?

If it originally came with Windows XP and it has the recovery partition still untouched (assuming the disk hadn't been formated to only one partition), you might recover the system from the hidden recovery partition.

To initiate this process, switch on the laptop and press F10 when the ACER logo appears (some computers need you to press ALT and F10 together, instead of the F10 only. If the Acer Recovery Management starts, you just have to follow the instructions to recover your system.

If nothing happens after pressing F10 or ALT and F10, you will need to get a Windows XP installation CD and a external CD drive to reinstall the whole system.

In this case, first you have to enter setup by pressing F2 at boot time, as soon as the ACER logo appears in the screen. Then, you will need to switch the SATA Mode to IDE from AHCI.

Select: Main -> SATA Mode -> IDE

This is done to allow Window XP to see your an IDE disk and install the system.

When you get the external USB CD/DVD driver to use with a Windows XP installer CD, connect it to you laptop, switch it on and press F2 again to enter Setup.

This time, scroll over to the BOOT menu and press Enter. Scroll down to the last option USB CD- Rom and then use the F5 key to move it to the top of the boot list order. Then press Escape and then F10 and finally Enter. The computer will restart and load the CD and you can start the installation of Windows XP.

Hope this info may help you!

Pressing F2 on startup enters the Setup Utility and a password to that has been set up on your netbook. In any case, you can try pressing Alt and F10 at startup to get into Acer eRecovery Management which can then restore the operating system to its original factory condition. Be aware that doing the restore clears the hard disk partition containing the operating system and all user data will be erased.

Can't get the system to boot in any configuration

Hi there.
The system files have become corrupt so it won't start properly, the only option left for you to do is recover the system.
If you didn't get any recovery disks with the laptop then you must use the recovery partition.
As the computer starts you can try ALT+F10 or CTRL+F10 during the initial boot cycle - this will prompt the laptop to access the recovery partition on the hard drive.

Good luck
