on the monitor and failed to progress.
I found the following webpage: wiki.sabayon.org/index.php?title=HOWTO:_Restore_Grub2
I loaded the liveDVD into the DVD drive and booted into the liveDVD. I carefully read through and executed the "Quick Recovery" section. However, before performing the mount commands, I executed "vgchange -a y" in order to make the default volume groups available for mounting, in the event that I needed to regain access to personal data. As such, the execution went as follows:
- Code: Select all
mkdir -p /mnt/sabayon
vgchange -a y
mount /dev/sda3 /mnt/sabayon
mount /dev/sda1 /mnt/sabayon/boot
grub2-install --root-directory=/mnt/sabayon /dev/sda
I suspect that the use of "vgchange" had no impact on /dev/sda3 since it does not appear to be part of a logical volume or a volume group. I hope that this action didn't mess up the process.
I then unmounted /dev/sda1 and /dev/sda3 and executed "vgchange -a n". I then attempted to reboot the system. The system shutdown and I removed the LiveDVD. I then attempted reboot and again saw progress halt at

This is what "fdisk -l" returns for /dev/sda:
- Code: Select all
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT
/dev/sda2 206848 614399999 307096576 7 HPFS/NTFS/exFAT
/dev/sda3 614400000 615423999 512000 83 Linux

/dev/sda5 615426048 3907028991 1645801472 8e Linux LVM
so I don't see any significant discrepancy between the "Quick Recovery" instructions and the configuration of my system.
I don't know what the problem is other than I can't get the system past "GRUB loading..". I do not know if Win7 destroyed the MBR (Master Boot Record).
Can the experts here please provide me with advice on what I should do next?
Do I need to attempt the "Completely Reinstall and Re-Configure Grub2" section of the previously listed web link?
Is there a potential hardware issue here, and if so, how should I troubleshoot to determine that?
Once this is fixed -- assuming it can be fixed -- what can I do to preclude recurrence?
Thanks very much for any help you can provide.
