boot flag

Post by zkab »

I have 2 disk in my system - one SSD and one regular one.
My intension was to make a fresh installation and to install 'swap and /' on SSD and /home on the regular disk. So I did ... and installed Katya

All went OK but when I checked with Gparted it tells me:

1) sda1 (ext4) has mount point /home and no flag
2) sdb1 is swap with flag 'boot'
sdb2 is extended partition
sdb5 (ext4) has mount point / and no flag.

What I don't understand is - why has the swap partition the flag 'boot' and not sdb5 ?
I have no problem booting the system.

Boot flag is just for Window OS

Linux OS does not need boot flag.

ext4 and swap are a bad choice for SSD. Use ext2 file system with SSD and swap is better to be on the regular disk.

I had the feeling that controller Sandforce SF-2200 took care of garbage collect (TRIM) for a SSD.
How do I move swap to the regular disk without messing it up ?

Via liveCD / liveUSB using GParted. Just delete swap and resize the regular disk and make a new swap partition. After that all you can edit /etc/fstab file updating a swap partition information.
