I bought a Grundig 1452 b1n2 Laptop. It had Win8 x64 (2GB RAM, very slow) I decided to install Win7 x86 via USB (no DVD drive on the laptop).

After some struggle with the BIOS I managed to boot into linux mint live CD. I used GParted and deleted all partitions. (now, unallocated-gpt) Now I realized that BIOS is locked so I can't use legacy support. (boot type is: UEFI and isn't changeable) I prepared a USB for UEFI install but it returns with the error "Default Boot Device Missing or Boot Failed"

How can I install win7 or win8 x64 on this machine?

This sounds like an Instant Go device where the BIOS is device encrypted. Unfortunately we cannot verify that and decrypt the device since you wiped the disk.

I suggest you get Windows 8.1 back on the device because a) that is your only chance and b) Windows 7 would be slower than W 8.1 anyhow.
