A partition on a USB stick cannot be marked as active.

I am now using Linux Mint. On GParted, I unmounted "USB Drive" and right-clicked on it again, but "Manage Flags" is greyed out.

Another one, XIAOMI, is normal.

I have just re-partitioned "XIAOMI" and set FAT32 as "boot" via "Manage flags".

I showed you in post #5 that a USB does not have to have a partition table in order to have a partition. Without a partition table there can be no flags to manage in any OS because there's nowhere to write them. The only cure is to create an MBR partition table. The Diskpart CLEAN command will remove all partition information, after which you'll be able to use Diskpart, Disk Management or GParted to create a partition that does have a partition table.

Why have you not yet tried cleaning this USB and re-partitioning it?

This one, like your first one, cannot be managed. The first physical sector of the partition is sector 0 (so there is nowhere for there to be a partition table).



But this one has a partition with a first physical sector of 2048 and does have a partition table. In fact, these two examples are the same USB, before and after cleaning and repartitioning.

What is the reason for attempting to make the partition active?

I want it to be bootable in both UEFI and Legacy BIOS.

Done. By using DiskPart, I have created an active primary FAT32 partition and an NTFS partition.

The free and offset readings are strange 0B

The reading is normal now.

Code:

DISKPART> list partition

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
* Partition 1    Primary             22 GB  1024 KB
  Partition 2    Primary           6147 MB    22 GB

Under GPARTED the bootable partition is either marked boot for MBR devices or esp,boot for GPT devices.

Is the following "boot" for MBR or GPT? I have used GParted to re-partition the 64-GB device.

had to use my Linux Mint and the included GPARTED program to delete the partition and recreate as 64GB and format as FAT32. FAT32 has a Windows limit of 32GB but other means can overcome that.

GParted is not needed. Everything can be done on Windows. I have just used AOMEI Partition Assistant to create a 50-GB FAT32 partition and then used DiskPart to mark it as active and create the second partition.
