Windows 7: Corrupt boot sector?

02 Mar 2013   #11

windows 7

You kind of lost me a little, what do you mean i cut out system reserved?

System reserved is still there, yea, its not active because i made C active and moved the MBR to c: by using the windows CD and choosed repair 3 times, got a tutorial from somewhere. Did that because how i sed, system reserved was assign automatically the drive letter c and windows was assign drive letter d and the windows didn't start.
I reinstalled windows 3 times before i did that, got to pissed, then used acronis with a backup (i though windows was crashing from an other reason) and then i found out about the drive letters being all messed out. I didn't delete the partition and remade it, just format it. A friend suggested i format/delete the partition of the hole drive, but i really don't want to do that since i have a lot of stuff i need on it and its large, not something i can put on a few dvd's.

Anyways, the moving the MBR to C: worked for about 2,3 weeks till it happend again, then i came here for help.

Ps:what is auto drive selection?

I don't know why you're concerned about the System reserved drive letter. It can be removed in Disk Mgmt. We could have told you this before you moved the boot files to C.

But since you have already moved the System Boot files to C, boot into DVD or REpair CD to run a few Startup Repairs to see if it finds anything to repair.

Then if necessary work through these Troubleshooting Steps for Windows 7 starting with Disk Check.

windows 7

well, it happened again

I think the windows update might be the problems, messes with something, i closed the updates for now.

Anyway, the problem was the same, using disk part, i used the command list volumes, and volume c instead of having the system format ntfs it sed raw, all the other partitions sed ntfs.
Again, using diskpart, made the partition c active, then using the repair system 3 times, it managed to rewrite a new mbr on disk c and windows started normaly.
Hopefully with the updates disabled it will stop, if not, next weekend i will delete all partitions on the drive, format the drive and remake the partitions and windows.

What were the results of the Disk Check?

Why do you ask for help here and then ignore it? This is how you ended up abandoning your System Reserved partition based on wrong assumptions about the drive letter.

I also specified in #8 that you need to wipe the HD before effective reinstall, not delete all partitions or format which do nothing to get rid of possibly corrupt code.

The disk check was ok, no errors.
Also don't think that i was wrong about the drive letters, it is wierd that when i used acronis at boot it showed me the windows partition as d and the system reserved as c, also the fact that in diskpart it showed c: as raw and not ntfs, thats wierd.

For the moment i disabled the updates, also since i know that it works to remake the boot by running system repair 3 times, i have a temporary fix.
I really can't wipe the whole drive right now, i have like 100 gb of programs and stuff on it and can't really move it.

Always be sure to select Auto drive letter setting when reimaging with Acronis, so that it will let Win7 be C. Often times at boot the SysReserved partition takes C but that has no bearing on how it appears in Windows, where it should be hidden.
