Hi,
I had A4 bios version on my new XPS 13 laptop (Win 7 x64 , i7) and decided to update to latest version. After install A7 (L321XA07.exe), I got has blue screen right after the system starts to load.
I tried to execute previous A4 bios install in Windows Recovery Mode, but when try to execute L321XA04.exe file , I got error : "the subsystem needed to support the image type is not present".
How can I reinstall bios on my computer?
Cheers,
