I've got a brand new laptop with a 128GB SSD drive. I read that aligning the partitions to match the Erase Block Size of the SSD is important. I followed William Scott's guide SSD Tweaks in Linux and Aligning Partitions and my partitions ended up being:
$ sudo fdisk -lu /dev/sda
Disk /dev/sda: 128.0 GB, 128035676100 bytes
32 heads, 32 sectors/track, 244208 cylinders, total 250069680 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00037bd2
Device Boot Start End Blocks Id System
/dev/sda1 * 1024 206847 102912 83 Linux
/dev/sda2 206848 16985087 8389120 82 Linux swap / Solaris
/dev/sda3 16985088 250068991 116541952 83 Linux
Then I installed Ubuntu Natty and specified the partitions manually so that /dev/sda1
became the /boot
partition formatted with ext2, /dev/sda2
the swap and /dev/sda3
the /
formatted with ext4. After the installation the thing didn't boot, and I ended up in the grub-rescue console which doesn't make any sense to me. It's giving me:
error: invalid arch independent ELF magic.
grub rescue>
Have I done some mistakes during my installation? How do I solve the issue with grub-recovery?
