Windows 7: Messed up drives and partitions

23 Oct 2009   #1

Windows 7 Professional
Messed up drives and partitions


I seem to have messed up my drives big time.
I had Windows XP installed on C:\
Partitioned that drive, installed Windows 7 Beta on D:\
Bought a second hard drive
Partitioned it to to drives, E and F

I just bought the Windows 7 Pro Upgrade, made a fresh install on E:\ with the hopes that it would change E:\ to C:\ like the beta did on my primary drive.

It didn't, now my drive lettering looks awful and it's confusing me lol.

I don't need the Windows XP or the Windows 7 Beta installation (on disk0), I would like to combine those partitions back into 1 drive.

Is there any way I can fix this mess? maybe make my current windows location C: ?

Confused? I know I am... I've posted some pics, hope they can clarify what I'm talking about

Thanks for your help!

Hello Angloman,

Welcome to Seven Forums.

You can change the drive letters manually. Do you now have all three boot options at startup? If you manually changed the letters (in disk manager, rt. click on a partition and select 'change letter and path') then you could combine and format old C & D. Next you would have to remove the old boot options via 'msconfig'.

Hope this helps.

Thanks for the quick reply!

I do have all 3 boot options at startup, which I would like to get rid of. MSconfig only shows me the other windows 7 option, not XP but I'll get to fixing that later.

What I really want to do is transfer the bootloader to disk1, partiton 1 (F: Storage), and then completely reformat disk0.

Once that's done I can worry about clearing up the boot menu.

Any suggestions for how I can do that?

Every partition that is bootable will have a bootstrap so just make sure you are booted to the retail 7, and then delete both partitions on disk 0. Then you can repartion as you wish and remove the deleted OSes boot entries through boot in msconfig.

Weird the XP isn't listed and that it doesn't make the new 7 C: when it is the active OS.

Okay problem solved.

Made Disk1 active, rebooted and got the bootmgr missing error msg.

Disconnected Disk0

Ran the recovery CD, fixed it

Booted up fine, reconnected Disk0, still booted fine... now going to reformat disk0

In the end, my drive letters will be F, G and H instead of C D and E but whatever... for the most part everything's working.

Thanks again!

Glad you've got it figured. You can change the letters to whatever you like anytime.

I tried, I get to the point where it warns me that changing the drive letter could mess some programs up, then when I click OK it tells me the parameter is incorrect

I've messed up with dynamic partitions and I need to backup
I had a dual boot of winxp on C, and win7 on S. All partitions are NTFS. It was in this order: C, S, (ext4 7gb partition), F. I originally wanted to remove C and the ext4 partition, to have one larger win 7 partition. I had a lot of data I wanted to keep on S and F, and was pretty naive. I...

I messed up the partitions
OK. So I finally got bullied enough by Microshaft to get rid of XP and get Windows 7. I liked XP and knew my way around so it was with a certain degree of trepidation that I delved into Windows 7 to learn a "new" operating system they will eventually dump once more to over price the next version...
