做U盘启动linux

Scientific linux to usb

# dd if=/dev/sdb of=/tmp/mbr_sdb.bin bs=512 count=1

# fdisk /dev/sdb

Command(m for help):d

1

…

(删除分区,当删除完后)

Command(m for help): w (保存更改)

(如果显示信息不正确，拔出U盘重新插入，并找到新的正确的U盘标识)

# mkfs.vfat /dev/sdb –I (fat格式化U盘)

Create a Windows 95/98 MBR on USB memory stick, using ms-sys (). Ms-sys is available on recent SL LiveCD/DVDs or you can take the rpm for el4 from?/packages/ms-sys/.

# ms-sys —mbr95b /dev/sdb

Create a new partition (enter n): Choose Primary partition (enter p), Partition number (enter 1). The size of the partition should be at least as larger as the LiveCD/DVD you want to install on the USB device. Afterwards, change the type (enter t) of first partition (enter 1) to?W95 FAT16 LBA?(enter e), and make first partition?active?(enter a and select 1). Before writing the partition table to the USB flash drive (enter w), you can print the changed settings (enter p).

# fdisk /dev/sdb

Command(m for help):

n (新分区)

p

1

1 (必须为1)

60 (启动盘空间大小，跟距实际需要填)

t (改变分区格式)

e (FAT16格式)

a (做为启动盘)

1

w (保存修改)

Now format the first partition (/dev/sdb1) as FAT16. If you like, you can set a label with option -n

# mkdosfs -n SL-LiveCD /dev/sdb1

下载syslinux : /pub/linux/utils/boot/syslinux/

# wget /pub/linux/utils/boot/syslinux/3.xx/syslinux-3.82.tar.gz

# tar xfvz syslinux-3.82.tar.gz

# cd syslinux-3.82

# make

# cd linux

# ./syslinux /dev/sdb1

此时重启从USB 启动应该会出现(不出现就要重做上一步，出现拔出U盘重新开机进生下一步):

下载 livecd_sl54_gome_***.iso (只能是5.x 版本)

# mkdir -p /mnt/iso

# mount -o loop livecd_SL54_gnome_2009-11-20.iso /mnt/iso

# cp -rv /mnt/iso/* /mnt/usbdisk/

# cd /mnt/usbdisk/

# mv boot/* .

Rename isolinux.cfg to syslinux.cfg and delete the path “boot/“ in syslinux.cfg, spl
