I am new user from window to Ubuntu. I just had installed Ubuntu 12.04 LTS. I have 4 drives NTFS + 1 drive (c:). C Drive is 50-GB. I don't want to remove other 4 drives which are on NTFS. I have deleted partition of C changes it to EXT4 file system. I think i am doing mistake in "Advance Partition Mode"... Because i don't know, how to set "mount point" and "Primary OR Logical" options for 1 (50-GB) drive.. Can you tell me what i do now.
Note: I have installed Ubuntu 12.04 LTS twice. every time i did fully format the drive. But the second time i get the boot error too.
