Repair Install

Gotcha. Well I ran MBR Regenerator and all of my programs ran at startup. Thanks for your help!

Nice tutorial, Brink. Just wondering, since my Windows 7 is already activated and I don't have the product key, how can I activate it? Thanks!

EDIT: I found a product key on the back of the computer, is that the windows 7 product key I need?

Thanks, Brink! Worked like a charm! Needed to get rid of a stupid error message that didn't allow any of my programs to be used but this worked. Can't thank you enough. Thanks!

Hi
Thanks for the very good tutorial. I'm trying to help a friend sort out a slightly flaky install of Windows 7. After trying many solutions to kick it back into 100% operational mode, I decided to try the repair install as per the instructions here. Since his original install was from a non-SP1 64-bit OEM DVD version of 7, I downloaded the ISO as per the instructions and burned a DVD. The process all goes swimmingly well until the 72% mark of the transferring settings part, then I get the dreaded "not enough disk space error".

So, here's what's been done with no success:
1) Clone 320GB drive to 1.5TB drive. Free space now 1.3TB
2) Delete all temp files. Do full defrag using Perfect Disk
3) Manually set VM file to suggested size (having min & max figures the same so the VM file is static). Then did PerfectDisk boot defrag to make VM file contiguous.
4) Switched Virtual Disk service to auto
5) Uninstalled MSE AV
6) Did chkdsk - no problems
7) Ran sfc /scannow. Keeps failing at 57% but I figured that's the whole point of doing the upgrade (which is essentially the old XP-style "repair install) in order to fix such problems.
8) Found that the 100MB partition that W7 makes is missing (which is odd). I recreated that to 256MB size and named it as per other instructions found. I didn't assign the partition a drive letter.

The only possibility I'm tracking down now is the following: I found a post on a website that said if a person creates the 100MB W7 partition using Easeus Partition Manager that W7 has a problem with that. I didn't create the partition using Easeus, but I did use Easeus to move the partition I created from being AFTER C: to BEFORE C: like it should be. What I'm going to try next is deleting the 256MB version of this partition that I made, re-jig the main partition so that only C: exists there (taking up all the room), then re-create the 100MB partition (think I'll got with 256MB again just to be safe) but this time only using the W7 manager and I'll just leave the partition where it sits, which will be after the C: one.

Has anyone else got any other thoughts on how to sort this? While a format / reinstall is do-able, it'll be a pile of work for my friend (as in, many days, possibly a week or 2), as he uses his machine to test many programs for his students. And, let's face it, who REALLY wants to go through the hassle of a full reinstall if they can avoid it?

All help and advice welcome.
Thanks

the upgrade stopped with an error message that it cannot update registry
