Mint OS hang by booting from a USB using PLOP.

[khurramjavaid94]

I am new to plop and linux. I download plop, burned it on the disk (Not the latest version but 5.0.10). Booted the disk selected, selected USB as device to boot from . It boots from my usb but hangs at the Mint OS intro screen. Nothing works and i have to cut the power. Is the OS causing problem or boot manager. Everything works fine in the manager. Also i have Dell Optiplex 745 that do support booting from usb but i can't find it. Its not in the boot menu. How can i fix this.

Sorry for my bad English.

is there an usb keyboard connected?

[khurramjavaid94]

Yes.

[khurramjavaid94]

I have tried both mode 1 and 2 on force USB 1.1.
If it do not support USB keyboard then how i am supposed to use the OS..??

[Elmar]

Yes.

i explained it often and i posted this a few days ago in another forum:

usb keyboards are working as long as you do not use the boot manager usb option.

why?

the keyboard is handled by the bios usb driver before you use the boot manager usb option. when you use the boot manager usb option, then the usb controller is not longer controlled by the bios -> no usb keyboard support by the bios. the boot manager has no usb keyboard driver -> no usb keyboard is working. when windows/linux is booted, then their usb drivers are taking control -> they have usb keyboard drivers -> the usb keyboard works again.

so you cannot use your keyboard when the boot manager on the usb drive has been started -> you have to add a timeout on you usb drive to boot the system without using the keyboard

Oh! Got it. Thanks for the help.

P.S This thing rocks.

To bad my PC don't support old School keyboards.

[khurramjavaid94]

I know the info that i gave ain't enough. but again i am new to this linux stuff.

[Elmar]

do you have a syslinux.cfg on the usb drive?

[khurramjavaid94]

Lemme search.

[khurramjavaid94]

Found it...Now..??

[khurramjavaid94]

Opening the file in Notepad i found this "timeout_msg 0 #ffffffff" I am guessing adding time out has something to do with this..

Heres all in the file.

add "timeout 100" below the "default vesamenu.c32".

100 = wait 10 seconds

more infos/options see syslinux homepage
