Just curious, were you running a 32 bit version of Ubuntu? In any case this page at Partition Magic may help. Also did you download the media creation tool from the Windows 11 page here?
Hello, I need help installing Windows 11 on my Dell Vostro laptop. When I bought the laptop, he came with an Ubuntu operating system installed with it. But I wanted to make a change, and go from Ubuntu to Windows operating system and install a Windows 11 on my laptop. I'm trying to install Windows 11 with a USB bootable drive, but I get the message: Windows cannot copy files required for installation. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007000B I have formatted all the drives on the disk, disk is clean and prepared for installing Windows, but it's not working. I have also changed the BIOS setting from RAID to AHCI in order for the SSD drive to work and to be recognized when I try to install Windows 11, but this is not helping either. I don't know what else I can do, but I really need to fix this urgently cause I need my laptop! I don't have a spare one to use in the mean time, and it's quite urgent for me to have a laptop that is working! Someone, please help and share the solution of this problem, if possible.
