Clarify if I understand boot files
I have a mess of usb boot drives, many that have lost their paper labels and many where I forgot to label them when I created them. Uefi drives, mbr drives, supposedly combined uefi and mbr drives. Some formatted ntfs, some as fat 32. These drives were made using different methods; media creation tool, rufus, yumi, directly from the apps themselves. I need someone to clarify that what I think I know is correct, because the longer I deal with this the more confused I get. Here are my questions.
For Windows Installation USB Drives
1. If I use powershell get-disk and find a drive is partitioned gpt, it’s automatically formatted fat32 and only PURE uefi bootable…correct?
2. If a drive is formatted ntfs and partitioned as mbr, then it is only mbr bootable…correct?
3. If a drive is formatted as fat32 and partitioned as mbr, to find if it is both uefi and mbr bootable, I have to look for the boot files within. For uefi boot, there will be \efi\boot\bootx.64.efi file and for mbr boot there will be a \boot\etfsboot.com file…correct??
For Bootable tools USB Drives (ie: Macrium rescue or a Yumi multi-tool disk)
1. If they are formatted fat32 and partitioned mbr, there will be Boot and EFI folders with same file names as above in them if they were built on windows platform or in the case of a Linux boot disk or Yumi multiboot which is built on Linux platform, the grub files in both folders. Therefore they will boot both mbr and uefi...correct?
My goal is to combine some of these using yumi and to do away with a lot of them.
