Creating a USB stick for installing centos 6.x using DVD1 and DVD2 iso files












3














First, we create 2 partitions on the USB stick that
is let's say 16GB.



first partition is let's say only 1GB

and the second partition is the rest of what is available.



after we "w" write the changes, the USB now has 2 partitions.




  • 1 is 1GB

  • 1 is more than 14GB


so , we have... sdb1 and sdb2 now.



now we need to turn these partitions into filesystems
some say i should run these commands after those procedures.



mkfs.vfat -F 32 /dev/sdb1
mkfs.ext3 /dev/sdb2


but some web pages recommend using:



mkfs.vfat -n BOOT /dev/sdb1
mkfs.ext2 -m 0 -b 4096 -L DATA /dev/sdb2


which is it?



so let's say the DVDs are called:




  • CentOS-6.4-x86_64-bin-DVD1.iso

  • CentOS-6.4-x86_64-bin-DVD2.iso


so we make a directory:



mkdir -p /mnt/dvd1


and then mount it:



mount -o loop CentOS-6.4-x86_64-bin-DVD1.iso /mnt/dvd1


and i suppose we don't make a directory for dvd2 and we don't have to mount it ?



at this point i do not know what should be done.



but i think this step might be next:



we make the USB bootable by finding the file named mbr.bin and then moving it to there via these commnad.



dd conv=notrunc bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdb
parted /dev/sdb set 1 boot on


in other words we are "dd-ing it to 'sdb' not sdb1' or 'sdb2'.
and then we use parted to set the boot to on for sdb



so far everything looks good?



here is the confusing parts..



how exactly do i move these iso files to the usb drive?



EVERYTHING BELOW IS A GUESS.



so at this point i should




  • copy the folder /mnt/dvd1/isolinux to usb's sdb1 or sdb2 ?

  • rename it to syslinux ?

  • and then inside this syslinux folder there will be a file called...

  • isolinux.cfg ?

  • which should be renamed to syslinux.cfg ?


  • and then copy the contents of /mnt/dvd1/images/* to USB's sdb2 ?



but i think i am also suppose to copy and paste the both




  • CentOS-6.4-x86_64-bin-DVD1.iso

  • CentOS-6.4-x86_64-bin-DVD2.iso


somewhere into this USB's sdb2 partition, correct ? almost like a drag and drop kind of a thing?



or do they go into any folders ?



centos' own web site has some instructions but those instructions do not work.

i once got this working but things got ruined, i have to do it again and this time take notes.

          You can use dd to copy burn the ISO in the USB stick. It's pretty easy and always work:



          Assuming the .iso file is in your home folder, open the terminal and write:



          sudo dd bs=4M if=[ur .iso] of=/dev/sd[that 1 letter]


          Example:



          sudo dd bs=4M if=centos.iso of=/dev/sdc
