[bug #38436] cannot find a GRUB drive for /dev/sda1. Check your Device Map

Follow-up Comment #4, bug #38436 (project grub): Zeroed a few MB on the start to test an installation script. But the script actually creates a partition. I'm going to try to recreate the problem. might be that the previous partition table was still in memory because the reread failed.

Follow-up Comment #5, bug #38436 (project grub): Most likely. And you also need to reserve space between MBR and first partition. For performance reason it's recommended to align at MiB boundary (e.g. put a start at 2048). ___ Reply to
