Got an Acer 4050 from ebay and it goes straight to enter boot password


can you click on f12 before it goes to boot password?
The F12 Boot Menu allows you to choose which device that you would like to boot the computer's Operating System from by pressing the F12 key during the computer's Power On Self Test, or POST process. Some notebook and netbook models have the F12 Boot Menu disabled by default.
If this sounds like your problem then try this:
If this sounds like
To enable the F12 Boot Menu:


  1. Restart the computer.
  2. Press the F2 key to enter computer's BIOS Setup during Power-On Self-Test, or POST, process while the Acer logo is being displayed.
  3. Press the Right Arrow key to select Main
  4. Select F12 Boot Menu
  5. Press the Enter key
  6. Select Enabled
  7. Press the Enter key
  8. Press the F10 key and then press the Enter key to save the changes and restart the computer.
Note: Not all Acer notebooks or netbooks have the F12 Boot Menu feature. Computers that do not have the F12 Boot Menu feature will not be able to enable the feature within the BIOS. I hope this works for you if not, then the problem is obviously not the boot menu. Go to Acer support for more help

BIOS Password Reset


if ti is a bios password the only thing you can try is to open it up and remove the bios battery for a minute or so ..and see if it works..It does not work for all models but usually for most desktops works and for some laptops..It basically cutting bios power and make it forget all settings including the password..After that just reinstall the operation system ..
If you are not sure if it is a bios setting ..just try to reinstall using a boot-able disk with the operation system ..and if the boot order is not set to boot first from CD ..just try to press f12 to engage the boot menu and select it manually ..and press enter ..
Another way to fool it ..is to try and remove the hard disk ...and force it to boot from the disk cause the disk is the next inline ..and after it starts just plug the hard disk again ..and you have a chance to go on with the installing in this time ..
let me know what you have tried and what worked..

Bootmgr doesnt work on my toshiba


If by boot mgr you understand the boot menu ..for to select the recovery or boot from disk ,,,it may need to go to bios settinsg by pressing F2 on start and in there look for the HOT KEYS .. and enable the f12 key or f11 after case..
If you are referring to a missing boot file ...and this massage is displayed when you try to ope (boot ) the computer ..it means the boot sequence is corrupted and you need to run the recovery partition or disk ..or reinstall the operation system from a boot-able disk ..
to do so ..go to bios and set the first boot device to be the cd /dvd ..save with F10 and restart with the disk inside..and press any key for to boot from cd ..
For recovery partition just press F12 on start and select the recovery partition for boot device ..or F11 if it has a direct recovery start by this key ..
follow the procedure and choose by the case repair or complete system installing ..
In second case you may loose data in the C drive ..including programs you have installed manually and were not installed by the manufacturer..
so ..if you want the files choose repair ..(either from recovery or from disk )
the command on repair if asked ..is fixboot ..(after you choose the hdd0 /windows)

When i turn on my laptop it ask for a password in blue and then there is a blinking curser and black screen it wont do anything after that unless i press f2 reapeatedly or f12 but i cant fix nothing on the...


There are two types of password:
1. BIOS password. To remove the BIOS password, the solution is, remove the BIOS battery. Location of the BIOS battery, the bottom of the laptop. So you have to unscrew the bottom of the laptop, find the BIOS battery and release approximately 7 seconds, then plug it back. Then, turn on the laptop, enter the BIOS by pressing F2, do the setting the date, time, etc.

2. Password Log on. When turning on the laptop, and log on, then we are asked to enter a password, but we never give password to log on. However, when we enter the password, always fails, it means the virus-infected operating system (operating system has been controlled by a virus). These cases often I meet, the Windows XP operating system is infected with the virus. The solution is to reinstall the operating system. Repair operating system, or breaking into password virus, I've tried, but always failed. So, the best solution is to reinstall the operating system.

If you are using Windows 7, you can fix with, insert the Windows operating system CD, then boot from the CD Room. Solutions you can do:

1.
Boot from CD Room, select Next - select Repair your computer - Next - select System Image Recovery

2. Boot from CD Room - select Next - select Install now - check the "I accept the license terms" - Next - select Custom (advanced). Then, select the drive where you installed windows - Next. Wait for your operating system install process to complete. Then enter your user name, etc.

After entering the desktop, don't open drive C, D, E, F, because the drive is still infected with the virus. All you have to do is, connect your laptop to the Internet, download anti-virus. You can use free anti-virus (Avira or AVG), then anti-virus updates. After the update is complete, do a virus scan, drive C, D, E, F. If a virus is detected, Primary action = repair, Secondary action = delete.


After drive C, D, E, F clean from viruses, you can open the drive C, D, E, F. You don't have to worry about losing data, because Windows 7, will backup your data in a folder Windows.old. In Windows.old folder, there are three folders: Program files, Users, Windows. Data stored in My Documents, can be found in the Users folder.

My computer won't boot, I just get a black screen that gives me two options, bios menu and something else f2 or F12


iF you cannot resume with the Operating system..try to go to Bios and set up the boot priority 1 = hard disc,

If this wont still work, your Operatiting system might be corrupted.. go to bios again and set up the boot priority 1 = cdrom.. next, try to insert the installation disc of your OS but do not install it, select option: REPAIR only.

If the cdrom would not boot, unplug the battery of the bios, then put it back again correctly. After this, boot again your cd.. Thanks..! dont forget to comment if you like my post.

Dell dimension 5100 original partitions have been wiped .. Now need to reinstall xp . I can not. Selected boot device not available. can not do ctrl-f11 anymore of course btw just in case you were thinking...


If you are getting message the message "selected boot device not available" that is because you have do not have a bootable HDD (Hard Disk). Please do the following:

Insert the Windows XP Operating system Disk.
Restart the computer and start Tapping the F12 key, It will give you the boot options.
Select to boot from CD/DVD-Rom
When prompted press any key to boot from CD-Rom
Once the computer is booted from CD, follow the instructions to install the Operating system.
Note: You can also go to BIOS (by pressing F2 or Delete) and change the boot device to CD-ROM

Once you finish installing the Windows Operating system. You can go ahead with installation of your Linux Operating system. After you finish Installing Linux you will get the option in GRUB to select the Operating systems.

If you have already installed Linux and want to install the Windows, Follow the same procedure but it will directly boot Windows after you finish Installing Windows. You will have to write the GRUB again for your Linux system.

Please get back for any further assistance.

Thank you for choosing Fixya.

No operating system found


If the error message says "No operating system found" it is most likely a faulty disk controller or a faulty hard disk.
Reseat the hard disk, if this doesn't work you need to test the hard disk another way. Remove the hard disk and connect it to an USB hard disk adapter and connect it to a working computer's USB port. If this computer sees this as an external hard drive and you can open the folders and files then the hard disk is OK and the fault is the disk controller on the the 4115c laptop.
If the hard disk is not detected then the hard disk is faulty. You need to install a new hard disk, install Windows and the laptop's device drivers and programs to get a working laptop again.
