XPS-15 OS restore fail - 'Windows Could not parse or process unattend answer file'

Hi, I have the Dell XPS-15 9570. I installed Linux Ubuntu on it, to hopefully dual boot, but encountered problems trying to get Windows to load as the RAID disk setting had to be changed. I also had issues with the BitLocker constantly asking for its key (which I have) - I thought it best to just reset the whole machine. I had some trouble getting Dell OS System Recovery to work, but eventually it went through the steps of completely reinstalling Windows via the Cloud. It appeared to successfully download and install, and went through the final boot. However, on this final boot, and any boot since, the OS won't complete setup - it presents an error 'Windows Could not parse or process unattend answer file [C:\Windows\Panther\unattend.xml]'. Hitting 'ok' simply reboots the machine, and the error returns. Looking at the BIOS, Ubunuty appears to still be there which I thought was odd as I presumed the Dell OSrecovery would totally wipe everything. Any ideas of where I can go now? I'm happy to have everything wiped, I basically just want a fresh install of Windows to work. Many thanks.

I just hard reset the machine and started from scratch, was the only way forward.

Also, if I replace the SSD, would that get rid if BitLocker, or is that 'feature' tied to the motherboard? I'd like a bigger hard drive and it would be good to get rid of the headaches BitLocker gives me. Thanks.

I changed the boot order so Windows booted first, then went through the Dell OS recovery procedure. This time it installed and I can now thankfully get into Win10.

Sorry, the problem has now returned - I thought changing the boot order had done something.
