Dual Boot Installation Not Seeing Partition

Support
1

Hello all. New to these forums and to AlmaLinux. I am attempting to do a dual boot install on Windows 11 machine. I have a bootable USB drive with the 9.5 ISO on it, and I can start the installation, but there is never an option for ‘Install alongside windows’, and it only shows the C drive as the destination and not the 100GB partition I created. I’m afraid if I install here it’s going to wipe out Windows Boot Manager / Windows Files, as I’ve seen on the forum as well.

Here’s what I’ve tried so far:

  • Created 100GB Partition
  • Disabled Fast Boot
  • Disabled BitLocker and Decrypted Drive
  • Disabled SecureBoot

I’ve read through the Support forum, but don’t see this one mentioned anywhere. The computer is an ASUS Zenbook 14 OLED UX3405MA with Windows 11 Home.

Here are my questions:

  • Is there a boot alongside option for AlmaLinux? I know there is for Ubuntu.
  • Is there another way to accomplish dual boot this if not part of the standard AlmaLinux installation?
  • Will a Custom Partition work, or is that just going to partition the C drive.
  • Does the format of the partition matter? I saw a note about XFS being the preferred format for Alma.

Thank you!

In Windows? AlmaLinux installer cannot use existing partition. It has to create new partitions to unallocated part of the drive.

Go back to Windows and remove the (unused) partition. Then boot the installer and check what it then could do.

That did it! Only needed to shrink the drive. Delete the partition and it saw it at the install.
