Booting PLD/DOS from USB pendrive 3

Create partition on your flash drive (using fdisk or cfdisk). Mark one of partitions bootable in fdisk/cdisk. Format that partition with FAT/FAT32 filesystem:

mkfs.vfat -F 32 /dev/sdXY

where sdXY is your partition.

Mount it and copy contents of PLD RescueCD like x86 and x86_64 ISO image to that partition, to /rcd subdirectory.

Make MBR record:

ms-sys -s /dev/sdX

(where sdX is entire flash disk; ms-sys comes from ms-sys package)

Copy syslinux configuration for USB to root directory of your flash drive as syslinux.cfg. DOS/Windows image should be placed in /rcd/boot/dos.gz (compress it with gzip first).

Run:

syslinux -s /dev/sdXY

to load syslinux onto your flash drive.

Reboot your system and check if it boots correctly

Note that some systems have problems with booting from flash driver (especially big like 1G or 2G flash drives).
