I have a notebook with two internal hard drives: one is SSD 128 GB with win10 (ms office, games) and other HDD of 1 TB currently unallocated space. I would love to install ubuntu on the other drive, but only on a part of it. Practicaly, to do a ~ 300 GB partition where to instal Ubuntu (swap and all it needs) and ~ 700 GB partition that could be shared between both (music, pictures, movies, some documets). Is it possible to do so and, if yes, how to do it? I didn't dual boot since xp, so it can't be to detalied :)

  • UEFI or BIOS install of Windows? Is sdb drive also in same partitioning i.e. gpt for UEFI and MBR(msdos) for BIOS? Either way you need to use Something Else and be sure to boot installer in same boot mode as Windows UEFI or BIOS. askubuntu.com/questions/743095/… If UEFI. & help.ubuntu.com/community/UEFI & askubuntu.com/questions/591193/… – oldfred Apr 4 '17 at 15:57
  • UEFI install of Windows. The other disk is still completely empty. Atm is MBR, but I do have the option of convert to GPT - if I understan correctly, if I do that and follow the link you provided, I should have no problems and/or four partition limit? Also, do I need to phisicaly detach the first disk (with Windows) before ubuntu installation? (suggested by some guides) – Charol Apr 4 '17 at 21:03
  • If you use Something Else you do not have to physically disconnect. It just is many times users do not understand partitions and/or choose an install option that erases entire drive like full drive LVM or encryption. I would change to gpt, and partition in advance & still use Something Else to choose/change which partition is / (root). With UEFI grub only installs to ESP - efi system partition of drive seen as sda. If you do not want grub to shared Windows' drive's ESP then disconnect Windows drive. – oldfred Apr 4 '17 at 23:54
