PEBuilder screen resolution in PE boot

I use pebuilder 2.0 to make 32- and 64-bit ISOs with the Win/10-based
creating environment downloaded.  I then add these ISOs to a USB key
created with easy2boot and test with two UEFI-only laptops.

On my 64-bit laptop, WinPE comes up with 800x600 resolution (native
is 1920x1080) and no way to change it.  That would be ok for some
maintenance tasks one might do from a PE boot, but Backupper 5.7 does
not adapt to the small screen.  The main window is bigger than the
screen but can be moved around.  But if I select options, buttons to
close are off-screen and there's no escape.  The option "Enable
program window self-adaptive to screen resolution and DPI settings"
that I see running Backupper on my desktop is not present in WinPE.
Adding what drivers I could find at ASUS didn't help, and I see no
relevant BIOS options.

Fedora 32 KDE spin from USB key gets native resolution on the same laptop.

On a 32-bit laptop, WinPE comes up with the native 1368x768 resolution.

Any suggestions for either increasing the resolution or making Backupper fit on a small screen?



  • Hi Wssddc,
    How big size is the screen of your 64-bit laptop? Is It the same size as the 32-bit laptop?

  • The 64-bit laptop is an ASUS VivoBook F512D, 15" screen, 1920x1080 native resolution, AMD processor, Windows 10, 10 months old.

    The 32-bit laptop is an ASUS X205T, 11.6" screen, 1366x768 native resolution, Intel Atom processor, Windows 8.1, old, cheap ($99) , under powered.
  • If I make a UEFI Backupper boot disk with version 5.8, I see the message "Failed to change current desktop size" as it's coming up.  So it is trying  to get a better resolution.
  • Never mind.  If I let Backupper write to a usb key directly and don't make an iso for a multi-boot option, I get native resolution (as well as the message failed to change desktop size).  So easy2boot is somehow triggering this and it's not your problem.  I will continue to fight with this on the easy2boot side.  It's so much nicer to have one key with a dozen boot options than a dozen keys.
  • @Wssddc, Thanks for your feedback. We will also submit the problem to our technician to test and check further.
  • An update on the easy2boot side.  If Backupper or PE Builder make a bootable USB key directly, and you drop the icon for the key on easy2boot's MPI_FAT32 shortcut, you get an imgPTN file which works and doesn't have resolution problems.  Making an ISO file from Backupper or PE Builder and converting that does not work.  Thanks to the easy2boot author for a useful email discussion about this.  Easy2boot 2.x and the optional a1ive menu system are required.
  • @Wssddc, Thanks for your feedback further.
