Did anyone mention the awesome Plop Bootmanager?
I use it to boot my usb(s) and my usb-cdrom on two computers
a Toshiba 7000CT (old) lappy and a old emachines PC.
Neither will boot from USB, but Plop can get around that
So, Plop can be used to simply boot the USB (plpbt.bin)
or it can be installed to MBR (plpbtin.bin) and act kinda like Grub
so, are you saying the computer in question has Windows already?
as Plop works(can work) from the Windows menu too.
If the computer has no OS installed, and only one USB port
like my lappy..., but does have a floppy or cd drive
then, you need to use the plop floppy or cd to initially boot the external HD
I simply put plpbt.bin on my HD and boot it from the Grub menu, then boot the USB from the
heres my grub menu.lst entry for Plop
note that any Linux OS you install will overwrite Plop (plpbtin.bin) if you installed Plop to MBR, meaning grub/lilo will remove plop when they install.
theres alot of docs at the sight too.
EDIT: in order to install a Linux OS, any, to my lappy, which had no OS at all and cant boot from USB
I used Plop bootfloppy to boot My USB, which had the Slack 12.2 mini iso on it
i booted into slack command line, started the install, then at
"mount cdrom", I quickly disconnected USB, connected usb-cdrom with slack cd-1 in it, then pressed enter for it to find cdrom
I tried using the usb images,etc
so finally tricked the lappy by replacing usb with usb-cdrom
to enable install.
Once you have any OS on there, installing any other os becomes possible.
