Syslinux + UBCD, not working

#1 Post by flyingsilverfin » Sun Dec 26, 2010 6:31 pm

I've got UBCD and ubuntu 10.04 dual-booting (on seperate partitions) on a USB stick. However, the problem doesnt seem to originate from that. For some reason (im using syslinux 3.63 i think) when i boot i just get a boot: prompt, and i don't know what to enter there to get the syslinux menu(s). It used to work, i dont know what changed. Sorry about the lack of background information :(

any help appreciated (an explanation of how syslinux operates would be nice too)

thx

When the "boot:" line appears, try just pressing <enter>.

One (of many, really! ) topics about syslinux with several links could be http://reboot.pro/13462 if you are interested, but the <enter> key should be enough to at least display the menu, which is your simple goal.

UBCD won't work with syslinux 3.63. you need to install the version included in the UBC?D iso (not for your Ubuntu partition).

for some reason when i try to do ./syslinux in the /ubcd/tools/ubcd2usb/linux/ folder it says "bash: ./syslinux: No such file or directory"
Doesnt work after i've moved it onto my desktop or anything either... even though it completed it with the tab-key auto completion. Can i just update my syslinux thats installed on ubuntu or is it necessary to use the one provided?

For UBCD, you should run the syslinux installer included (v4.02 I think).

It you read the readme.txt in the ubcd2usb folder (linux), you see:

Code: Select all

7. Install syslinux to the partition of your USB thumb drive.

   First make sure that ./ubcd/tools/linux/ubcd2usb/syslinux is executable, if not, run:

     chmod a+x ./ubcd/tools/linux/ubcd2usb/syslinux (adapt the path if nessecary)

You need to make sure that your are in the right path before executing it.

Where did you extract the UBCD ISO to (which path)?

Note: if the syslinux command succeeds, it doesn't show any output.

Also note that the syntax for installing SYSLINUX, changed recently: (X = dirve letter, n = partition number)

Code: Select all

./syslinux --install -d /boot/syslinux /dev/sdXn

I was in the directory.
Does it work on 64-bit systems?

It should work.

To run 32-bit executables, you need to install the 32-bit libraries too.

You can also compile a 64-bit installer:
- Download Syslinux 4.02 and extract it: ftp://ftp.kernel.org/pub/linux/boot/syslinux/4.xx/
- cd to the extrqcted directory and build the installersM

Code: Select all

make clean
make installer


Can you post all commands you ran?
