How put window vista back to factory setting without a disk

Not possible without disk unless you have it loaded on a separate partition on your computer!

If you tried to install Vista on the Primary drive and formatted the primary HDD your Factory Recovery Partition , most likely has been written over, it's gone. Choose one or the other , Vista or Win 7, start from the beginning, install a clean Vista load, formatting in the installation procedure, form a Vista Installation DVD, follow instructions, boot up, do ALL the Vista Updates, it will take hours of updates, rebooting, updates, rebooting. You will get to the Service Pack's 1 and 2, in 24 hours or so. Put on a pot of coffee and be patience. If you prefer Windows 7 use the same procedure.

Try running the check disk utility.

To run the check disk utility you will need a repair disc or a operating system disc. Put the disc in the cd drive and boot from it. You want to get to the Dos Command Prompt (Black screen with white letters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice the percentages going from high to low, this is normal. Let it run to completion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows. Try doing a Repair Install that way you don't loose your data, documents, music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair when the options appear.

In Vista and Windows 7 you want to get to the recovery console and look down at the bottom of the window for the Dos Command.

You'll need to read your manual to see how to start the Factory Setting. Look for the manual on your manufacturer's website.

Get online and got to www.google.com In the google search box type: "Acer Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Look for Manuals and search them for Factory Restore or System Recovery.

OK
You have Vista

EASY

In CONTROL PANEL select RECOVERY

Then "Advanced Recovery Settings"

Then "Return your computer to factory settings".

Be AWARE you will loose all of your files and after market downloads.

For the first one, you need to enter BIOS and set the HDD settings. Maybe you can automatic detect it once and then the system knew where to load system from. If it can see the hard disk and reads it but no operating system found, then you may need to check the operating system on your hard disk.
For the second one, I do think it is better to upgrade to a upper level OS such as Windows 7. While you have Vista you will have better deal with Windows 7. If you do have a agreement with Microsoft to have newer OS for free in a certain period, you can get Windows 7 for free. If you don't have that agreement, you can get Upgrade version of windows 7 with a huge discount if you have Vista.
You can actually back up your data to an wim file on vista and restore all the data and settings after the upgrading. But be sure to keep a full backup of your hard disk and everything just in case.
You can enter BIOS and make sure booting from CD first. Then there is a key you need to press very early in the booting process to launch the recovery. There is also a factory default restore you can use. Did you call HP to find out what the key is and how to use factory default restoration? You can always plug the hard disk to other computer to back up the data and then restore to factory default and put the data back.

if you have it saved on part of your drive i belive its f10 on the boot up failing that use a o/s :ie xp vista windows 7 disk and re-install it.

Hello,

If you used the restore disk on your computer it will erase all files, and all your programs. the restore Factory settings means "ALL" settings the time you created the CD for the restore.

If you have an individual Vista Installer CD with the Serial you can use it and use restore option.

Thank you for using Fixya
Hope this helps.

take any of vista disk(any copy)
boot with cd in repair option get restore click.

You need the disk to do so. Else you format hard drive install New Os download drivers from Website. ( Before this see the modem type display card drivers lan card drivers Etc.)
