Hi,
my new laptop came with Ubuntu installed. Now I want to install Win10 from an USB Stick.
I created the USB Stick following this guide: www.tekrevue.com/.../
To boot from the USB stick, I had to disable Secure Boot and enable Legacy Boot in the BIOS.
When the Win10 installer showed me the partitions, it also said that it couldn't install Windows on that drive, because it was not a GPT partition / not GPT compatible. Only after I removed all exisitng partitions (including the DELL EPS partition - which might have been a mistake?), I could repartition the drive successfully and install Win10.
Now I wanted to switch back to UEFI Boot in the BIOS, but this doesn't work: When I switch to UEFI and click on "Add Boot Option", a message comes up saying "File System Not Found!". After that, the system doesn't reboot anymore unless I switch back to Legacy Boot.
So I am kind of stuck - what could be the problem? How could I boot in UEFI mode from the USB stick? Or is there a certain setting in the BIOS I am missing?
Thx for every hint!
Oliver
