Can you please check the following:
Press Windows-R, then enter msinfo32
. Now check for the following Information:
- BIOS Mode
- Secure Boot State
Additionally, do you have administrative privileges on your computer? I ask these because the Installer assumes on your installation that it has been bootet with UEFI but is unable to mount the EFI Boot partition which is kinda strange:
14:38:05 - EFI system with 64-bit Windows; assuming x64 EFI (which is ok)
14:51:47 - C:\projects\rufus\endless\src\endless\EndlessUsbToolDlg.cpp:6262 CEndlessUsbToolDlg::MountESPFromDrive
14:51:47 - C:\projects\rufus\endless\src\endless\EndlessUsbToolDlg.cpp:6276 Unexpected partition type. Partition style is not GPT (GLE=[0])
14:51:47 - C:\projects\rufus\endless\src\endless\EndlessUsbToolDlg.cpp:5732 Error on MountESPFromDrive (GLE=[0])
To verify your partition structure, please also run diskpart
and enter the following commands:
lis dis
sel dis 0
-
lis par
Should look like:
Please post all requested information ideally with screenshots.
