I made a 80GB partition in windows in the C disk but in the Ubuntu installator I can't find that, it shows me only a freespace partition with 0 MB. Installator neither detects windows to check the option of install along with windows boot manager.

Also the partition is GPT format and static (not dynamic), both systems start in UEFI.

I already deactivated BitLocker in the C disk viewing possible solutions, also I deactivated fast startup.

Partitions shown in Windows (the free espace of 78GB is what I want to view in Ubuntu, created from C disk):

Partitions shown in ubuntu installator:

  • Ubuntu cannot use Windows partitions. Is 80GB actually NTFS? Leave the 80GB as unformatted unallocated free space. Also make sure Windows fast start up is off which sets hibernation flag. If not the installer may not see the NTFS partitions. – oldfred Aug 06 '23 at 02:32
  • In every guide to make this you have to create partitions, so I created a 80GB partition in windows, and according to disk properties is NTFS, GPT and static (not dynamic). I added information in my question like photos and console outputs if you can help me please. – BitShifter Aug 07 '23 at 01:57
  • Windows cannot create Linux partitions, never seen any instructions that say to create a Windows formatted partition for Linux. You do show an ext4 partition which Ubuntu can use. But Windows partitions are not shown. Do you have Windows fast startup or bitlocker on? https://askubuntu.com/questions/1460440/my-other-drive-still-has-windows-files-after-installation-made-sure-not-to-dual https://askubuntu.com/questions/843153/unable-to-mount-windows-10-partition-it-is-in-an-unsafe-state – oldfred Aug 07 '23 at 02:30
  • I said in in the question, yes, I had bitlocker on but I deactivated it and tried again but nothing changed, also I deactivated the fast startup option, futhermore I tried to install it shiuting down windows with shift but none of that worked – BitShifter Aug 07 '23 at 02:54
  • GPT as I said and according to the disk C properties – BitShifter Aug 07 '23 at 03:14
  • What happens when you select sda and hit the +? Does the installer offer to make a new partition, allowing you to change the default size (probably shows a max of 80G)? – ubfan1 Aug 07 '23 at 04:14
  • It won't let me, sda according to a text in the ubuntu installator is the USB drive, futhermore it has too low space to be the disk. See my second photo in the question. Anyways there are more details about it in the console outputs that I put above. – BitShifter Aug 07 '23 at 22:32
  • Nmve is the disk but I'm afraid of lose data creating someing on it, because the + button is not enabled and it asks me to create a new table of partitions and I don't know what that could do. – BitShifter Aug 07 '23 at 22:44
