I have an 8 gig ssd Dell vostro that has been running ubuntu linux successfully for several months. Linux is the only O.S. on the machine. Wishing to have more room I inserted a new 32 Gig SDHC card in the card slot and did an ext4 format and then did an install using the 10.10 disk that did the original install. Everything seemed to proceed as expected, but it rebooted using the 8 Gig drive. The 32 Gig card appears to have all the proper files. How do I get it to boot from that card?

Change boot priority to usb or removeable media in bios.

Many thanks for the reply.

I can see the card with 10.10 ubuntu on it by clicking "places". It is listed as "32 GB file system".

When I looked in media, one file was present:
ac504950-2eab-47a5-8292-319f9d4b383a

Since I don't know how to do what you suggested I followed the directions in a file that I found at:
help.ubuntu.com/community/InstallingANewHardDrive

When I tried to boot, the message "serious errors were found while checking the disk drive for /media/mynewdrive" came up.

I see three possibilities. If it isn't too much work (I suspect it is) would you tell me how to do what you suggested. If not, could you recommend a procedure that I can find on the internet? The third possibility is for me to go back to google and try to find something or perhaps try above reference again.

Side note: Here it is less than 24 hours since my original post and it is already listed at Google. Amazing!

Perhaps the error can be found in the procedure I used to try and boot from the 32 gig drive.

The 32 gig drive was formated as ext4 before installing ubuntu.
(It appears after clicking “places”, along with home folder etc.
)

Installed 10.10 umbuntu

Created a mount point:

sudo fdisk -l #(to dermine the disk name
(result: Disk /dev/mmcblk0: 32.5 GB, 32462864384 bytes)
sudo mkdir /media/mynewdrive #create a mount point
gksu gedit /etc/fstab
#add a line to fstab

/dev/mmcblk0 /media/mynewdrive ext4 defaults 0 2

A reboot resulted in the login screen with the following message:
“serious errors were found while checking the disk drive for
/media/mynew drive”
Typing I for ignore ran the normal boot.
