Are you using the same windows installer usb you used to originally install windows? Did you have windows installed when you purchased the computer? Are you now using an iso you downloaded from the microsoft site and wrote to the usb?
A windows system won't recognize much of anything regarding a Linux system. In Disk Management on an installed windows, you should be able to see the drives and partitions but won't be able to access anything. I don't know what tools you have available on the windows installer.
I just tried the gpt partition table. I tried unpartitioned and formated using ntfs and neither show up using my windows 11 installer
What does tried the gpt partition table mean? Did you change it from msdos to gpt? I would have thought it already was gpt, did you check first? How (what tool) did you do this? Did you create a partition (or partitions) on which to install windows? How did you do that, what tool did you use? Something on the windows installer? Probably best to leave the entire disk as free or unallocated space.
If you still have the Ubuntu install usb, you might try booting it and running either command below to get and post the output here so we have some actual information:
Code:
sudo parted -l
sudo fdisk -l
Another suggestion, since this is not a Linux or Ubuntu problem but a user error, you might be better off at a windows forum or checking the microsoft site for possible solutions or at least suggestions.
