Hello everyone. Need help.
I have an 640-GB USB Bootable WD Hard Drive with Grub4DOS and some useful tools for my work. Over 3-4 years all works fine, sometimes (3-4 times) grub brakes, but every time I restored it via BOOTICE (Installed Windows NT 5 MBR then installed Grub5Dos MBR and boot came back again - it simply rewrited).
But at the last week my boot sector was brake again and the BOOTICE-method doesn't help me: even after Grub installing I get the NO GRLDR error (while grldr-file was on the hard drive).
What I did for resolving this issue:
- trying to reformat my HDD via Acronis (of course, with copying all my 460GB-data to another harddrive) , then installed Grub4DOS. All works fine for 3 times, but after 3 boots I get NO GRLDR again.
- trying to reformat with RMPREPFORUSB and installed Grub via RMPREP - result is the same (NO GRLDR after 3 boots).
Of course, I checked my harddrive for errors and bad-sectors - nothing bad!
Somewhat breakes the MBR Boot record, can't trace it, so the questions:
- how can I protect the MBR Boot record (Grub boot record) from changes and writes?
- how can I quckly restore Grub Boot record WITHOUT repartitioning or reformatting? There is a lot of pain to copy all my work data (over 400 GB) every time I trying to restore boot. How can I drop the NO GRLDR error without reformatting?
Thanks a lot for all your help!!!
