Hi, I am running a dual boot system with Windows on sda1 and Fedora 8 Linux on sda3 since quite some time. I am using the standard MBR, Grub is installed on the active partition, sda3. Recently I noticed that my boot block was defect. There was a possible reason why this could happen (upgrade of PGP WDE on Windows), so I wasn't overly surprised. No problem, grab the rescue CD reinstalled Grub and the system was up again. Windows and Linux were bootable again. Except that, after I worked the next time on Linux (meaning: the next time I did more than simply booting up and shutting down) the same thing happened again. Ok, reinstalled Grub, checked that Windows and Linux are bootable again and so far so good. But finally, after actually working with Linux again today, I found myself confronted with a blank screen with the word GRUB in the upper left corner again: Third time destroyed boot system in a row. Any ideas what's happening? Thanks, Jochen -- Look, that's why there's rules, understand? So that you think before you break 'em. -- (Terry Pratchett, Thief of Time)
