Infinite restart loop

Wow, I didn't know you can do that as well!

Thanks again!

Do you see it listed in All Programs? Try making the disks. It may need to be reset.

Are you using MS Security Essentials? It is lightest, least intrusive AV and will cause the least troubles.

But I just F...D my Windows 7 boot....
I had 4 partitions... 1. 100mb system, 2. win 7 Ult x64, 3. extended, 4. extended
I installed Backtrack Linux on 3d. partition, and now everything is fuc...d up...
PC doesnt boot at all,... it just writes "GRUB" all over the screen in an endless loop,...
I cannot boot in win nor linux.
I tried all of the above with absolutely no results.
I even deleted the 1. system partition,.... still the "GRUB" loop
I tried repairing more than 3 times as said before,... with no luck at all

what can I do?

Why would you delete the System Partition, which is required for Win7 to boot.

You'll need to mark Win7 partition Active and run Startup Repair up to three separate times with reboots until it starts up.

Partition - Mark as Active
Startup Repair

hi guys,
thanks for the link,.. but it didn't help...
I even deleted all of the partitions, than made 2 new partitions, formated them,...
restarted just to be sure the GRUB loop is gone,....but I still get the GRUB,.. not the loop but written just once, until I reboot again,....
finally I installed windows again, and that made the GRUB problem go away...now it boots just fine,...
Im clueless what happened, but Im glad it worked, cos for the moment I thought I would need to replace my HDD...

GRUB corrupts Win7 when installed on the same HD.

Best to add a second HD if you want to dual boot with Linux, then use BIOS to boot into either HD.

Thanks for the link....
it will come handy for sure....
