Grub is really cool!
AS I already wrote I made a small upgrade of my home PC: I boutgh LCD display and new hard drive. I installed the hard drive as a master and an old one as slave. The problem was I had two OS on the old disk – Linux and Windows and used GRUB as boot loader. After adding new hard disk and installing Windows there I couldn’t boot Linux anymore. I had to change boot options in BIOS to boot from slave disk and use Linux. It was terrible! Thanks to Yoshinori K. Okuji for excellent tool GRUB. I just loaded GRUB shell:
chose root (hd0 – master, hd1 – slave, but because I booted from slave it’s hd0 and master – hd1):
Filesystem type is ext2fs, partition type 0×83
and copied GRUB files to the master hard drive:
As result I can boot new or previous version of Windows and Linux! Thanks to GRUB and Linux
