Weird Yet Pleasant Finding On USB Booting
For as far as I remember since the introduction of UEFI Bios management system of hard drives and I keep reading the following quotes everywhere and following them blindly :
When Windows can’t boot from USB, you need to make sure your bootable USB drive is formatted in the FAT32 file system if your computer supports UEFI and you are attempting to install Windows in UEFI mode. That is, you cannot use a USB drive with the NTFS file system to boot and install Windows in UEFI modeSource : What If Your PC Can’t Boot from USB? Follow These Methods!UEFI specs define FAT32 as mandatory
Another : I'm unable to boot my Windows 10 installer USB in UEFI mode? - Super User
Another : windows 8 - UEFI Boot a NTFS Drive - Super User
etc etc
Now I have always been finding this a weird approach by Microsoft as the Fat32 system is obsolete compared to NTFS (File Size and Permissions) , and usually my uses for USB Booting revolves around attempting to recover crashed systems or extracting important files using Windows PE Environment Or Recovery Disks deeming this a troublesome approach since files larger than 4 GBs can not be recovered on same USB Flash Drive / Pen Drive , which are usually what I am trying to recover or are worthy of recovering (Database Files , Project Files , Video Files etc) leading to the problem that I need to plug another Media to recover these kind of files and hopefully I am not short on ports .
Now suddenly I came across a very weird finding ...
You can actually boot into UEFI using NTFS (GPT or not) judging that the booting Port is USB 2.0 .
So Apparently the FAT32 restriction was enforced by UEFI as a policy but not a system limitation as they persist to mention , yet apparently in that policy they forgot to ban the USB 2.0 ports from booting to UEFI in NTFS format .
I further took it to the test that if a system has no USB 2.0 using small 2.0 Hubs as an interconnection (converter) between USB Flash Drives / Pen Drives and a USB 3 port do the trick too (Might be Hub type / brand dependent though , others need to test and report too as mine was a vanilla Hub just laying around from years ago) .
Now the down side to this process is the following : While it surely opens for recovery of large files it limits the recovery process to the USB 2.0 speed , making it an iffy job still to recover a large data file at 28 MB/s or so , but might be a useful mean in dire situations like the one I had that lead to such finding .
Now I honestly hate how once again we are lead like sheep in a world of weird secret policies but keep copying what we are being told and consider it professionalism .
Cheers
