But I always got the notice to make the stick bootable (the
last one was 8GB)
Does this mean
- the sticks are no good?
- I'm doing something wrong?
- what kind of stick is ok?
Hi;
Become root, then do an "fdisk -l"
Insert the stick, wait a couple of seconds and repeat "fdisk -l"
You should see your USB stick:
[mick@localhost ~]$ su -
Password:
[root@localhost ~]# fdisk -l
Disk /dev/sdc: 2003 MB, 2003828736 bytes
43 heads, 42 sectors/track, 2167 cylinders
Units = cylinders of 1806 * 512 = 924672 bytes
Disk identifier: 0x04030201
Device Boot Start End Blocks Id System
/dev/sdc1 1 2168 1956800 b W95 FAT32
Now that you know which disk it is do: "fdisk /dev/sdc" NOT sdc1, then "p" to see what is there:
[root@localhost ~]# fdisk /dev/sdc
The number of cylinders for this disk is set to 2167.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/sdc: 2003 MB, 2003828736 bytes
43 heads, 42 sectors/track, 2167 cylinders
Units = cylinders of 1806 * 512 = 924672 bytes
Disk identifier: 0x04030201
Device Boot Start End Blocks Id System
/dev/sdc1 1 2168 1956800 b W95 FAT32
Command (m for help):
Now make it bootable with the "a" flag, and "p" to make sure it worked:
Command (m for help): a
Partition number (1-4): 1
Command (m for help): p
Disk /dev/sdc: 2003 MB, 2003828736 bytes
43 heads, 42 sectors/track, 2167 cylinders
Units = cylinders of 1806 * 512 = 924672 bytes

Device Boot Start End Blocks Id System
/dev/sdc1 * 1 2168 1956800 b W95 FAT32
Command (m for help):
Do you see the star/asterisk under boot?
Now write it out to save it with "w" which will also exit fdisk:
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
[root@localhost ~]#
Now unplug it, wait a bit and plug it in.
Do another "fdisk -l"
Disk /dev/sdc: 2003 MB, 2003828736 bytes
43 heads, 42 sectors/track, 2167 cylinders
Units = cylinders of 1806 * 512 = 924672 bytes

/dev/sdc1 * 1 2168 1956800 b W95 FAT32
[root@localhost ~]#
There you go.
