How to fix corrupt boot files in WIN 7 Pro 64 biy installation

trinaz · 04 Jun 2011

After trying a repair install per the Repair Install Tutoiral...I can no longer boot my PC. If I boot to the Win 7 install CD I get a "Windows can not boot error" with a message about the boot file being corrupted.

If I let the system boot directly...I get a screen with 2 choices for the operating system:

Windows Setup
Windows 7

This started after a repair install failed to complete. If I choose Windows Setup I get a Windows Repair Install screen with a pop up message saying Windows can not start (boot) ?

If I choose the second option on the boot screen...I get my normal Win 7 system...whether clicking Windows 7 OS...or using the more options link choosing boot from last good installation...or start up normally via the F8 option.

Is there a way to undo whatever the repair install did to the system before it failed to complete the repair install ?

Thanks

Try deleting Windows setup in System Configuration.

Hello mate.

You may be able to use bcdedit to remove the "Windows Setup" entry from the boot menu if you can't boot the PC normally to do it in msconfig, the OP isn't clear whether Windows will actually start normally.

Use the method in this tutorial at the link below to boot the Windows 7 DVD and open a command window, though instead of entering diskpart when the command window opens enter bcdedit, then from there you can edit the entries.

DISKPART : At PC Startup

Then use this tutorial for the info, I'm going to add the correct command below, you would substitute your entry information though.

bcdedit /delete {your entry number}

How to Use the BCDEDIT Command Line Tool

This snip below is of my booted bcdedit for reference, to see what yours should look like, if you have any questions be sure to ask.

When you get done it would be a good idea to export a backup of bcdedit for safe-keeping.

Then you may need to do the 3 separate startup repairs to Windows to get it booting normally; have a look at this tutorial at the link below, be sure that Windows 7 is the Active partition first, have a look at Option Two for that.

Yes...I can boot normally to the second of 2 item at the OS select operating system screen...which is Windows 7.

Everything seems to be running/working fine in Windows 7 (second choice at startup)...but..Windows setup is the default OS because if I do notheing...the Windows Setup (1st option at startup) screens starts up...not normal Win 7.

Thanks guys...before I start on this there's one more thing...I deleted the other folders created during the failed repair install...but I can not remove/delete the Windows.old folder (see attached jpgs) I keep getting an error that the folder no longer is there...but obviously...it's still listed in the C:\ directory ?

Is this and issue and should I correct this firs...if so...how ?

So you can start Windows 7 up successfully?

trinaz · 04 Jun 2011

Yes...if I choose the second OS (Windows 7) the system boots OK and seems to run fine...If I reboot and do NOT select either option ( (1)Windows Setup or (2) Windows 7)...the system reverts to the Windows Setup startup type screen.

Does this not work?

trinaz · 04 Jun 2011

Yes...it did work...I was/am just concerned why I can't delete the Windows.old folder as the last post's jpg shows ?

Also...any thoughts on why my repair install would fail and go into the loop shown in a previous topic when this all started ?
Trouble doing a tutorial "repair install"

I have done 1 or 2 repair installs before without issue ?

Thanks...Tim
