I personal a number of PC and on a few of them, I’m able to boot to Home windows installer utilizing a USB flash drive formatted in NTFS (similar one for all of the PC), however not for others.
PC that I’ve tried this on:
(in a position to boot from NTFS) Desktop with motherboard ASUS PRIME Z390-A and a Ninth-Gen Intel Core processor
(not in a position to boot from NTFS) Floor Professional (5/1796) with i7-7660U (a Seventh-Gen) and corresponding motherboard
(in a position to boot from NTFS) ASUS ROG Zephyrus M (GM501) with Intel HM370 Chipset and i7-8750H (an Eighth-Gen processor)
All of them have CSM disabled (or just unavailable) and the USB has a GUID Partition Desk (GPT) and solely a single major partition.
From the knowledge I gathered on-line, UEFI-based PC will solely boot from an EFI System Partition or a FAT32 partition. However the proof from my expertise clearly tells me in any other case.
Why is that?
