USB boot does not mount my partitions

Post in this forum for problems at boot time, if there was no problem for burning the disc. For example can't find the CD, or strange errors when you press enter at the very first prompt.

USB boot does not mount my partitions

Postby sunsetbrew » 11 Jun 2009, 15:01

I am creating a USB rescue stick based on the Linux/ext3/grub example. However, during boot I get this message
Media not found


So I added a large root delay to the kernel command line which still did not work.

In the mini-shell I found /dev/sdb but not /dev/sdb1 and etc. This suggest that the device was found at least but the partitions devices were not created. So I did a mknod for sdb1 and was able to mount the partition. Any idea why this is not automatically being created? Being a rescue disk the device could be sda, sdb, sdc and etc.


Here is the list of devices (/dev/sd*)

Code: Select all

brw-rw----    1 0        0          8,   0 Jun 10 16:32 /dev/sda
brw-rw----    1 0        0          8,   1 Jun 10 16:32 /dev/sda1
brw-rw----    1 0        0          8,   2 Jun 10 16:32 /dev/sda2
brw-rw----    1 0        0          8,  16 Jun 10 16:32 /dev/sdb


Here is /proc/partiions

Code: Select all

major minor  #blocks  name

   8        0   15761088 sda
   8        1   14707476 sda1
   8        2    1052257 sda2
   8       16   15794176 sdb
   8       17    1060258 sdb1
   8       18    3156772 sdb2
   8       19    4200997 sdb3
   8       20          1 sdb4
   8       21    2104483 sdb5
   8       22    2104483 sdb6
   8       23    2104483 sdb7
   8       24    1060258 sdb8


Thanks in advance for the help!!!!

It looks simple: you have to create partitions on your stick. You can use the sysresccd-usbstick script for that:
