i have a 32 gigs usb drive and, given that most isos are around 2-5 gigs, it’s such a shame to see nearly 30 gigs of perfectly good free space go to waste whenever i need to use it as a bootable drive. is there any way i can burn an iso image to the usb drive while still being able to use its free space?

    If you don’t want Ventoy:

    Wipe the drive and partition it so the first partition is large enough for your ISO, then the second partition for your data spans the remaining space. I chose MBR over GPT so I could boot on both modern and legacy BIOS machines. Then dd your ISO to the first partition. Set the bootable flag on that partition if it isn’t already. Format the second partition with whatever filesystem you’d like.

    My Clonezilla recovery drive is set up like this, but it’s been a while so I might have forgotten something. Let me know if I did.

    Edit: this will not work with Windows ISOs and the data partition won’t show up in certain versions of Windows, in case anyone is wondering

      it didnt work sadly. all i got was a blank screen

      edit: actually i think i got it right this time, i just needed to format it as an empty partition on gparted. brb edit 2: nope. blank screen again (even though the dd’d partition got recognized by gparted this time)
