I tried root (hd0,4) and geometry in the very beginning - that's why I said that grub4dos did not see my Linux partition. I get Error 5 - invalid partition. But Kubuntu live cd and GParted on UBCD see it and mount it just fine. Gujin (from UBCD) even boots it (almost to very end). Since there are already a few recent unresolved threads on this forum about getting into grub4dos prompt instead of Linux - I'd say the problem is with grub4dos rather than my partition.Coolname007 said:What happens when you run these commands at the Grub4Dos prompt:
My system is just 2 year old and completely standard and generic. I used a very popular MSI mobo, all SATA controllers are from the mobo chipset. The system is rock-solid and not even over-clocked.
The order is guaranteed only with IDE drives. The order of SATA can easily change, e.g., when hot swapping (or when controllers and their timings are different). The sdX order is how SATA present themselves to the kernel. This could really play havoc with the boot, but that's why grub2 works with uuid in grub.cfg rather than a fixed sdX or hdX order. At least that's my understanding after reading this wiki on Persistent block device namingThose same SCSI IDs stay the same from then on, I believe, regardless of whether one device is disconnected and then reconnected back, or else the computer would get all confused and the boot would probably always fail.
So, what could possibly trip grub4dos? ext4? A 2 TB hard drive with the partition at the very end?
