Depending on what that drive was prevously used for I may do a clean all.
Like for instance if it was used to boot up one of my Raspbery Pi's.
Diskpart is the default Windows systems command line disk partitioning utility.
To demonstrate on how to create disk partitions in Windows using diskpart command.
Then switch to Disk Management to create a New Simple Volume and format etc. Here is the issue I am currently at: I have a Surface Pro 4 that I want to set up a Dual Boot on.
Then finally go back to Diskpart to make the partition Active. 4/8 GB RAM I recently revitalized my friends HP 2000 laptop. I normally wouldn't have too much of an issue resolving this on my own, but due to the Surface Pro 4 not supporting Legacy flash drives, my standard...I believe that marking the partition as "active" is unnecessary with a UEFI system. Just do a quick format of the USB drive as Fat32, mount the (which can be done natively under Window 8, 8.1, and 10), and copy all of the contents of the to the USB drive.That would do if you only ever want to boot on UEFI systems. A full format will write to every location on the usb and may reduce its life. It's a useful precaution in case the usb has previously been used with Rufus and ended up as GPT. Like you say I use the convert mbr command just as a precautionary measure.Im presuming a Full Format would pick up on any issues on the flash drive whereas a quick format wouldn't flag up any possible errors etc. Just out of curiosity.it also possible to use Disk Management to prepare the flash drive?You would have to Clean the drive and Convert MBR using Diskpart first.The process has proven to be irreversible so you should always proceed with care. Follow steps below to create disk partitions in Windows using diskpart command.To run diskpart, press Windows key X keyboard shortcut.diskpart list disk select disk # clean convert mbr create partition primary select partition 1 active format fs=fat32 exit Many Thanks https://docs.microsoft.com/en-us/win...sb-flash-drive I've never had to use the "convert MBR" command.The link above formats as NTFS, but you need to use FAT32 to make the drive bootable from the UEFI.Then switch to Disk Management to create a New Simple Volume and format etc.Then finally go back to Diskpart to make the partition Active. diskpart list disk select disk # (enter flash drive number) list partition select partition 1 (this would be the only partition on the drive) active exit I use diskpart to create my install drives, and use the active command.
