    Has anyone run into a GRUB Loading stage1.5Read Error on boot. It seems about half the time i boot/reboot i get this error and the other half grub loads up fine. I am running a 32GB Compact Flash card with a CF to ZIF adapter. I have tried reinstalling grub many times with different options. I know the setup and config are correct because it works sometimes. I could find only one similar error via a google search http://www.mail-archive.com/bug-grub@gn ... 05815.html I may try LILO at this point but would prefer to keep GRUB if i can figure out a fix.

    Read up on the "Boot process" here ...

    http://en.wikipedia.org/wiki/GNU_GRUB

    You'll see that stage 1.5 is the partition table of the drive (first 30k after MBR). When grub reads this, it knows where to find the stage 2 files which of course reside on the hard drive. A read error suggests that there is either some problem with the partition table or possibly it's having a problem reading from your /boot directory to launch stage 2. I'm not sure which is the problem. You might try running fsck on your hdd to see if that fixes it.

    Cheers.

    Still unsolved, i will be installing a fresh copy of the Windows 7 beta in a few hours and will report back if the same issue arises.

    Well, that oughta do it. Repartitioning and building a fresh filesystem should work, unless something screwy in the way the CF card moves the sectors around for wear-leveling is the problem. I thought LILO was high-level enough that it'd be transparent though.

    If a superblock's bad, it's going to need repartitioned anyway. fsck (usually, like 95% of the time, in my experience) can't fix that. If the MBR's broken, fsck might fix it, or you might just rewrite it.

    Strange errors in windows 7 now, it works for a few reboots then goes into a recovery console loop that it cannot resolve (saying its a registry corrupt error). I am at a complete loss. May have to try a different CF card or just go back to the 8gb ssd :(
