Windows 7: linux killed my win 7

linux killed my win 7

my son tried putting linux on my acer pc while I was out one day, only for me to find out afterwards, that Windows 7 will not boot up... I get the start up bit after selecting windows from the lilo prompt for a dual boot, then it goes into (I am guessing, the start of) setup, after which, the pc kindly informs me, that it can not continue, but will continue after restart, only to end up back in the same circle all over again...
I have been informed it maybe the MBR, though I have my doubts about this...
Also, in my neglect, I have failed to make any kind of recovery/back-up discs... however, if I boot up a live version of unbuntu, I can see all my windows stuff still there (having tried to install ubuntu over last linux in an attempt to fix windows, but that failed too)

any other info needed, please ask...
in meant time if any one can help, that would be great.

many thanks for your time.

Hopefully Linux was installed to a separate partition. You'll be able to see better when you boot in to make sure the Windows 7 partition or it's 100mb System Reserved partition (preferred) is marked Active: Mark Partition Active.

Then from the Windows 7 DVD or System Repair Disk run Startup Repair - Run 3 Separate Times until Windows 7 starts on its own.

You can have a picture of what you're doing using free Partition Wizard bootable CD: How to Set Active/Inactive partition with Partition Wizard Video Help.. If you use PW CD then click on Disk # to highlight it, from Disk tab select Rebuild MBR, Apply. If this fails to start Windows 7, run the 3 Startup Repairs from DVD or Repair CD.

Be aware that GRUB bootloader on the same HD can corrupt Windows 7 beyond repair. If Windows 7 won't repair you can rescue your files and get a superior Clean Reinstall - Factory OEM Windows 7, or run Acer eRecovery from it's partition or disks you made or order: Acer Support: Frequently Asked Questions list for Recovery media and Restoring a system to factory load

win 7 64bit (home)

thanks for the info...
when i boot up to live version of ubuntu, and take a look in the gpart program, it is showing...
system reserved, acer and data as all being set to boot, would this cause a problem?
if so, which one/s should be set to boot, as I am sure I could change these so that one or 2 if need be are boot.

thanks again for your time.

Use the methods I gave you, Diskpart from the installer or Repair CD, or Partition Wizard. GParted is old school.

Hi Mog -

If you'll post back a screenshot of your maximized Disk Management drive map, using Snipping Tool in Start Menu, we can give you the steps to safely remove the other Windows 7.

You shouldn't have had to search for the latest Windows 7 installer ISO if you followed the steps to get a perfect Clean Reinstall - Factory OEM Windows 7

hope this is the image you was asking for...
C: drive is the good side, and D: is the bad...
ideally, I would like to remove all data from D: and merge the two partitions.

If you didn't follow the steps in Clean Reinstall - Factory OEM Windows 7 as would seem to be the case since you didn't delete the old OS partition, then I would do it over and get it right since there are many steps given which assure best performance and maintenance of the OS.

If you stuck closely enough to the Best Practices given in the tutorial then to now get rid of D you would boot free Partition Wizard, rightclick on D to Delete, click OK.

Next rightclick on C to Resize, drag left border all the way to the left to take up the space created when you deleted D, click OK, Apply all steps. Partition Wizard - Resize Partition - Video Help.

Make sure you back up your data and a Windows 7 backup image first as resizing operations can fail although we have never had PW CD fail in countless thousands of these operations since before Windows 7 release.
