>>I have a Tandy 1000EX that's been in storage for over 5 years. I bought some Tandy MS-DOS 5.25" floppy disks from a seller on eBay. When I insert his newly made boot disk in the internal 5.25" drive and turn on the computer, instead of booting up it displays the message "Boot Failure". The disk drive light turns on and it sounds like it's operating correctly. Do I need to clean the disk drive? Do I need a different boot disk? If I add an external floppy drive can I boot from that? Is my internal floppy drive defective?

Yes you should have cleaned and lubed the drive first.
Yes the versions of MS DOS for Tandy were OEM configured
(Video and KeyBoard related)
The 1000 can run up to DOS 3.2 Tandy version, you can find various
Tandy DOS versions at win world pc. No am not a member/contributer
there but for free you should try there IF you can get your floppy
working if those other disks do not work....
