Windows 7: Change system partition?

05 Mar 2011   #21

Windows 7x64 Home Premium SP1

So Disk 0 is a dead duck at the moment after attempting removal of XP?
Do you have any system images?

Do you have any tools for examining disk 0 apart from system repair?
For some information on the status of the disk, again from the repair disk:
>list disk
>list volume
describe the output.

When you select recover from an image you can select install drivers not to install drivers but get a windows explorer like feature. You can look and see what you find on C:. Then just backtrack out of the install drivers.

list disk returns no fixed disks to show. list volume returns there are no volumes. And as far as I can tell, drive C: is non-existent. It only shows a drive called Boot (X: ).

Doesn't Partition Wizard show the disk like it apparently used to?

(also correction bootrec /scanos will not report an OS already in the BCD.)

Yes Partition Wizard is still able to display all the partitions correctly.

I've no idea why list disk & volume don't come up with anything.

From Partition Wizard
What's on the D: partition right now?
Is it still marked system
and C: is marked active?

Follow SIW2's advice several posts below to use PW boot CD Partition Recovery Wizard to attempt to recover the C partition to the beginning of HD.

If this doesn't work I'd boot PW CD, rightclick first 2 partitions + Unalloc space to Wipe (to get as much code off the HD as poss), create a Primary partition there, mark Active, Boot 7 DVD to install there.

Now install the latest EasyBCD version, click Add OS tab, choose Win7 on C partition, Save. Reboot to see if it adds to Boot menu.

Later we can help strip all of the files out of rescue partition except boot files, shrink it to a boot partition.

We can help try to rescue C as long as you want, but what are the barriers to wiping the HD now to re-install windows 7?

Do you have your files from Win7? Copy & Paste - in Windows Recovery Console

That's the strange thing about Partition Wizard. It shows all the partitions, but not their labels. I know which ones are supposed to be C: and D:, but they are not labeled C: and D:, it's just blank.

Following gregrocker's post. Can you do a clean install of Windows 7 on the disk?

Regarding the letter assignments. I suggest you assign your win 7 old C: the letter C using PW. Then follow the gregrocker steps. This may give you large system reserved partition which can be trimmed in size later.

So with this new active primary at the front and the OS marked C: (not active) try running the automated (System Repair) x3.

Are you able to run partition recovery from PW?

If not, I would d/l gparted, boot it up.

Download gparted-live-0.8.0-3.iso (123.5 MB)

Assuming it sees the partitions - take a screenie ( you will need somewhere to save it , so you can post it up ).

If you can't save the screenie anywhere :

use gparted to create a partition - inside the part of the HD that you don't need data back from - that would be the partition that held XP.

Make sure you only do that with the XP partition - don't stray over the boundary to the 7 partition.

When you have done that, boot PW again and run the partition recovery to recover the windows 7 partition.

Well I'd really like to try to keep my C: drive as intact as possible. For now I just used Partition Wizard to mark Windows XP as active again, and now I can boot into XP. Still can't boot into 7, but for a new reason. Now it says that Windows failed to start, gives some advice on how to fix it (it doesn't work of course), and this error information.

Status: 0xc0000225
Info: The boot selection failed because a required device is inaccessible.

For now could someone help me just get it so that I can boot Windows 7 again, and possibly find another way to get rid of the XP partition afterward?
