Re: Cannot install Grub2

[Артём А]

I changed a little my partition layout since your letter, but this didn't

helped.

$ sudo parted -l

Model: ATA ST3400620AS (scsi)

Disk /dev/sda: 400GB

Sector size (logical/physical): 512B/512B

Partition Table: msdos

Disk Flags:

Number Start End Size Type File system Flags

1 475MB 21.5GB 21.1GB primary ext4

2 21.6GB 36.9GB 15.4GB primary ext4 boot

3 37.7GB 367GB 329GB extended lba

5 39.9GB 116GB 76.2GB logical ntfs

6 116GB 119GB 2973MB logical linux-swap(v1)

7 119GB 367GB 247GB logical ext4

4 367GB 400GB 33.3GB primary ntfs

In both of these cases it's probably that you have left over bits from
previous filesystems/partition tables which make it impossible for
grub to ensure safety. We need to figure out what remnants grub is
seeing, and remove them (this will also likely affect other utilities
and so is a good thing to prevent data corruption in general).

Please provide the output of "sudo parted -l". Parted is familiar with
filesystems and is aware of many more partition labels than fdisk, and
will hopefully give us an error message which is more useful to fixing
the problem.
