By older I mean P4. The cost to replace optical drive exceeds value of device. Only the lexar lightning is recognized as bootable. It has a flavor of windows miniPE: not suited to install ubuntu I bet. But that usb thumb drive is useful so I have no desire to make it a liveboot of ubuntu.
How do I extract- or identify the whatsit properties that my old bios deem bootable but no dozen newer usb thumb drives are? Then how do I inflict those on a new usb thumb drive? or buy one that is?
What're some options for backing up (clone?) the lexar lightning usb thumb drive?
Being old the toshiba bios is as updated as it will ever be. The lightning shows as a removable device. I have tried using a single partition less than 2gigs on newer thumb drives known to boot newer machines. The plan was to post the usb vid
id but is has wandered off my desk. The internal HD was wiped a few years ago.
What additional information need I provide?
