If you reformat it ALL will be lost on the hard drive if that is what you reformat. Then you will have to do a cold start using the Windows installation disks from scratch. This is a LAST ditch thing to do.

To reformat the hard drive completely you will have to use the utilities on your Windows installation disks which you may or may not have. Make sure you have your serial number and the necessary stuff to re-activate Windows and ALL other software disks for all the programs you have been using. Also any data you have such as photos, etc must all be saved on other medi that you can reload after reformatting and reinstalling Windows...

I think it is UNLIKELY you REALLY want to reformat the hard drive in your machine... It may take you days of work and frustration to complelwtely restore the machine after a reeformat of the hard drive.

you mean restoring to factory default? re start your machine the press the BLUE Button right away this will prompt you to IBM Rescue and recovery.... unless your system is reformat on a OEM OS then you will need to have the bootable disk from IBM T60..

You are accessing the DOS command via your OS so of course your drive is in use.

Use the original install disc to reformat.

be specific please reformat the disk by reinstalling the os if you have file that you need get a different hd with the same os and use your old one as slave and save your files and thad reformat your hd

Hard disk needs to be reformatted--start machine and press correct key when "setup" appears in first dialog. Remove hard drive in first screen, then reinstall. Restart computer, should now say: "operating system not found". You need original Microsoft OS disk to reformat drive and reinstall ME. All previous information on hard disk will be lost with this procedure. Recovery disk is used with original OS before Ubuntu. If you don't have original MS disk, suggest going to XP.

you can use a licensed OS (vista or XP) for reinstalling the windows and download the drivers later

If your computer froze either on safe mode or normal mode to log in to windows it means the your OS (operating system) is corrupted. You might need to reformat your machine to it's defaulty factory settings. Note that all your files will be deleated if you will reformat it. Before reformatting I advice that you back up first all your files from another machine. To do this, take out your hard disk and connect it to another computer (it will detext as usb or external hard disk). After saving all the files, put the hard disk back to your machine and reformat it then.

Reformatting will wipe the drive clean and you will need to reinstall windows, either from the rescue CD or from other media. You may be able to contact Acer and order a replacement CD and install it using the OEM license originally sold with your machine.

If it is merely a problem that programs are not running correctly or that something has corrupted the computer, see if there is a good restore point that you can use from "System Restore." This may allow you to fix the problem and remove the offending program without having to go through the trouble of reformatting and finding the replacement disk.

Finally, since you say that it is Vista, it should be a relatively new machine and it may have a restore partition instead of a rescue disk. If this is the case, there should be a utility in your programs from acer that will allow you to restore the computer to its original form. This will typically reboot the computer and handle the format / reinstall for you. It's possible your friend can't find the disk because he didn't have one.

Just a heads up, typically you can not use a rescue disk from another machine (different make or model) as it will check the hardware configuration before installing the software to make sure it matches the machine the disk shipped with. It is not serial number specific though.

Hope this helps!

If you put a BootCD in the CD drive then turn the system on you should be able to format the HDD from the CD. Also, your new operating system disk should allow you to reformat the HDD. Just put the CD in and start the computer up again. Watch for a message to press the spacebar or any other key to boot from the CD.
