As stated in the title, Ubuntu installer does not recognize Windows 8 and it will not offer the "Install along with Windows" option. Only "Erase everything" or "Something else". How can I solve this?
Important details:
- My disk is GPT.
- I can see and browse Windows partitions (
OS
(C:
),System
, recovery etc.) just fine from Nautilus while in Live. I didn't have to mount them manually or anything similar. I can even write and read files. - GParted will recognize all partitions correctly
- No error is reported in
boot.log
and the disk is correctly mounted (i.e. nothing special indmesg
). - I have Secure Boot enabled. I tried with SB disabled and nothing changed.
- I have already resized Windows partition from Windows Disk Manager and created enough free space for Ubuntu to install (15GB)
- I am pretty confident that the USB key I use for booting Ubuntu is OK: the md5sum of the ISO was ok, I created the USB disk with
ddrescue
andsync
ed it before unplugging. - If I choose "Something else" from the installer, no partition is reported in the hard disk (so I cannot even do it manually and I don't want to risk blindly erasing the disk).
- Reinstalling Windows 8 is not an option.
- I would like to avoid DIY scripts and tools: I am not asking for anything special, Ubuntu installer should work the usual way. If some command-line-fu is needed, please include the relevant commands in the answer.
- The Live disk boots ok, and everything works as expected (I can install programs, browse the Internet with Firefox etc.).
- I am booting in UEFI mode.
