I decided to migrate from Ubuntu 13.10 to 12.04 LTS, so I have downloaded .iso image and wrote it to my USB-stick. During the installation, on a stage of partitioning hard drive, I met one problem.



I have two big partitions (Windows partition, partition for Files) and it's all clear about them. But I also have two small partitions. The first one is FAT32, 100MiB size and in it there are Windows bootloader files, Ubuntu bootloader files. The second one is 128MiB size, unknown filesystem, "msftres" flag.



What should I do in order to correctly install Ubuntu? As I know, I should choose the first 100MiB FAT32-partition as a EFI-partition, but I am afraid that Windows bootloader files will be destroyed. Please, help me.

If there's already an efi partition, you do not need to do any thing. Just mount it to /boot/efi. Then installer should do everything for you.



For me, sda3 is efi and sda8 is /boot,
so what I need to do is



mount /dev/sda8 /boot
mkdir /boot/efi && mount /dev/sda3 /boot/efi


finally it looks like:



housezet@arch: ~
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 260M 0 part
├─sda2 8:2 0 1.5G 0 part
├─sda3 8:3 0 260M 0 part /boot/efi
├─sda4 8:4 0 128M 0 part
├─sda5 8:5 0 845.1G 0 part /home/win
├─sda6 8:6 0 392M 0 part
├─sda7 8:7 0 33.9G 0 part
├─sda8 8:8 0 500M 0 part /boot
├─sda9 8:9 0 19.5G 0 part /
├─sda11 8:11 0 27G 0 part /home
└─sda12 8:12 0 3G 0 part [SWAP]
sr0 11:0 1 1024M 0 rom


and



housezet@arch: ~
$ ls /boot
efi initramfs-linux.img vmlinuz-linux


For 'msftres' flags, refer to this question:
Is it safe to format msftres, msftdata and hidden partitions?
