Moving Boot manager.

ryuu00 · 21 Jan 2011

I was reading this thread and instead of necro'ing it i decided i would make my own.

I'm having trouble with the whole "BootMGR is missing" error.

I was going to try use my SATA cable for a diffrent device for about 20-30 mins but after unplugging my storage HDD i got the Bootmgr is missing error and apparently my boot folder is on my storage HDD

So reading that thread stated above i tried moving the files from the boot folder over to my C drive and using the elevated command prompt to try fix it. The command prompt said it had done it correctly and i restarted windows and tried booting from my C drive but no, it didn't work.

This is my Disk management screen.

I'm unsure on how to move the boot folder to the C drive so it can boot without my storage HDD (X drive)

If you know how to move it please post!:)

Hello ryuu00 and welcome to the forums.

I take it the c: drive contains your main Windows 7.

Basicly you will need to rewrite the boot MGR for the C: drive.

Nice and easy - Follow this tutorial Startup Repair

Once you can boot into the c: drive, plug back in the ext. hdd and click start and type in the search box "msconfig" (Without quotes)
Go to the boot tab and make sure C: drive is the default boot OS, if not, just click on the C: Drive and then click "Make Default", click apply and then click ok and click restart.

Hope this helps.

Warning: Make sure you backup your Data first.

You may need to copy boot files from drive X to your Win7 drive.

1) Make sure you have these files on the Windows 7 partition.

2) Remove all HD's, leaving only Disk0.

3) Than do a startup repair.

Note: You may need to do startup repair 3 to 4 times.

You'll need to mark C Active first to get the Repairs to write the boot-critical files to Win7 partition. Copying the files is automated in Startup Repair.

While marking C Active , mark your data drive Inactive using Diskpart or free Partition Wizard bootable CD before doing the repairs: Partition - Mark as Active
