Partition

The partition of the USB drive looked like below. I probably had partitioned this before. If it doesn’t look like below, you want to use fdisk to partition the USB drive.

Disk /dev/sdg: 3880 MB, 3880452096 bytes
120 heads, 62 sectors/track, 1018 cylinders, total 7579008 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
Disk identifier: 0xe9ad0200
Device Boot Start End Blocks Id System 
/dev/sdg1 2048 292863 145408 c W95 FAT32 (LBA)
/dev/sdg2 292864 3710975 1709056 83 Linux

Images

cp kernel  /media/venkat/0243-8F11/vmlinux

Copy the kernel to the first partition
