Start OS In the 7720 i have a problem with start XP ... it's only work on a "emergency" My disk is ok, and all drives North Bridge could be broken ? :>

Your DVD drive may fail to appear for several reasons not least of which are hardware failure and corrupt drivers. Windows XP era machines are rather old and tired now, but you do expect their hardware to work.

To troubleshoot DVD drive start with a bootable CD such as an old OS or software installation disk. Put the disk in the drive and reboot the machine. If necessary go into the BIOS or press the appropriate key on your machine to force boot from CD before hard drive.

If the DVD software comes up, it means that the disk drive is intact and working. Your problem is with XP configuration. Run your system repair software. Microsoft gives instructions here: http://support.microsoft.com/kb/982116

However if it will not boot from DVD your drive or disk is broken or incorrectly configured. Time to repair or replace.

If you installed Linux successfully on your hard disk then the hard disk is OK.
If you are installing Windows Xp and it does not detect the hard disk but the BIOS detects the hard disk then -
The problem is that XPinstallation CD does not have a SATA driver, unless you have a SATA drive on adisk etc. and can install the driver when XP asks for a hard drive driver then,XP cannot detect the hard disk and therefore won't install XP.The FIX.Go into the BIOS anddisable the SATA drive (enable IDE emulation), this will make XP think it is aIDE/PATA hard disk. Then you can install XP normally. When Windows hasbeen installed then install all the device drivers (including the SATA driver),then shut down and boot up and got into the BIOS and enable the SATA drive.

Hi there,Your Hard Drive is faulty and need to be replaced. It will crash completely sometime soon so its advisable to get it replaced.

The first thing you need to do is repartition the hard drive. This will effectively erase the drive because partitions run below the OS level.

You create two partitions and then you can load each OS to its own partition. When the box boots you choose the OS you want to start and thats it...I think if you put the preferred OS in the first partition it will load that one by default.

You need both OS disks to do this so make sure your factory Vista disk works.

You need to enter the BIOS. immediately upon starting the computer start tapping either the F2 or the tab button. Once in the bios, go to boot order and set the cd/dvd drive as the first boot priority, hard drive second. It is ok to leave this permanently, save and close settings which will reboot the system and considering everything goes as planned you should be able to start up from a disk and then repair or replace XP. When replacing XP remember to delete partition and write a new copy. THIS WILL ERASE ALL INFO ALREADY ON THE HARD DRIVE!!!

Does the computer startup when plugged in? Try to remove the battery and plug it into a wall socket then turn it on. If it still does not start, the problem is not the battery. My initial thought if it's not the battery its the Operating System (OS) in your case Windows XP. I had this same thing happen to me last week after Adobe updated itself. What I needed to do was reload my XP OS. If you have the original restore disk that came with the computer, use it and reinstall XP. If you have files on your laptop that you need to keep and are not backed up externally, you will need to get those files extracted from the hard-drive before you reinstall the OS. This can be done by removing the Hard drive from the computer, make sure the computer is unplugged and battery removed before you do this. Take it to you friendly neighborhood computer geek and have He/She run the hard-drive externally to extract the files and place them on a disk or a flash drive. This is also a good time to have the hard-drive scanned for viruses or maleware so you don't reinstall the on the computer. Wipe the hard drive and start to reinstall. If this is more than you can handle, you can get someone locally to do the work for you and it shouldn't cost you more than $100.

Hello,

Nowadays the computer comes with the Recovery Disks inside on the Hard Drive for you to Burn on disks. The options changes from manufacturer to manufacturer, but try to bootup in safe mode with F8 key and search on start menu for tools related to the manufacturer computer (ex. On some HP is START | PC Tools).

Check when the computer is booting for options of recovery before windows starts.

Beware, in most cases you can Burn the disk once.

Do you want to try and see if a 'Linux LiveCD' boots? This is the way I test if the computer works. You burn this CD to a disk, and then boot off of it when you're computer starts. I will not modify anything on your computer as long as you go to 'Try Ubuntu with out installing'

http://www.ubuntu.com/getubuntu/download

Don't worry, I'm not trying to get you to install anything, just see if it boots into the 'live environment' (means you are running it off of the cd) If this works, that means that it is only your windows installation is messed up, and a reinstallation of windows should work fine with a Windows install CD NOT the recovery cd.

off course it is repairable dont worry look try to install OS thru the following procedure to factory default state

Acer: When you first turn on the laptop and see the Acer logo screen, hold the ALT key and press the F10 key (you need to do this before the Acer logo disappears).

if it installs the OS ok then fine if not

pls consider changing RAM take out from beneath the laptop open the cover all screws and take out the L shaped panel then u will see the RAM in front with 2 chips one uper and one lower side try to take out both and then re fit only one in the upper slot and then try to install if hangs again , then try the 2nd chip in the first slot and repeat the procedure if it works ok only try both chips one by one if it resolves ur issue and u find the faulty one replace it with new one with sam specs

in the last case if ur system still hangs then my friend ur hard disk is giving u hard time it needs replacement

when a system boots after bios loading all that is trf from Hdisk to RAM and then OS is loaded if one have problem system will hang or freeze try these solutions and then tell me the results

pls go step by step

and pls rate me fixya if i fixed ur problem

kindly let me know abt it and tell me in detail the messages u get and the system behaviour

You maybe having OS (OEM) issues.
You may be having drive space issues.
Recommend:
Verify that the hardware is supported by both OS on the Microsoft Campatibility site. If the controller and dirive checks ok then you will need to verify if you have at least 40 gig free space on the 80gig drive, if not, you will likely have to delete the partitions and start fresh with the XP disks. Caution: make sure that the manufacture supports the both XP and Vista on that machine and you have all the drivers you need.
