"Missing OS" on Acer Aspire 1300

[Elan67]

I've tried latest 5.0.4 plop BM on Acer Aspire 1300, trying to boot from diskette a 4 Gb USB pen but I stuck on "Missing Operating System", any suggestion?

Thanks

hi,
there are some reasons why this can happen.
maybe if your pen drive is FAT formatted then i think its not in LBA format.
is the partition activated to boot?
what system is on the pendrive and how did you make it bootable. did you partition and format it by your self?

thank so much for answer.
Pen is fat16 and here is parted output:

Code: [Select]

Disk /dev/sdb: 4043MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags   
 1      32.3kB  4043MB  4043MB  primary  fat16        boot, lba
Do you think there is something wrong?

Pen is booting right on USB boot supported systems.
Os is windows 2008 server installation dvd, of course I don't even think to install it with this notebook! It is just the only usb bootable pen I have around to test plop functionality.
I really don't remember how it was formatted/created, it was some ago.

the mbr program was not good. i think it was the original program from your pen manufacture.

you can fix this in the future with

Code: [Select]

lilo -M /dev/sdb
