failed to unmount partitions

Asked by texastop2003

i am installing ubuntu 9.10 and when i get to installing systems it gets to 15% and states "failed to unmount partitions" The

installer needs to commit changes to partition tables, but cannot do so becaue partitions on the following mount points could not be unmounted:

/cdrom

Please close any applications using these mount points

Would you like the installer to try to unmount these partitions again?"

i have 1 drive in my computer that is partitioned already and when i get to the partition screen it states

"your installation medium is on /dev/sda1. you will not be
able to create, delete, or resize partitions on this disk,
but you may be able to install to exisiting partitions there.

can anyone help me i have spent days working on this and i am new to ubuntu.

nevermind i found the solution and if you are planning to duel boot this is not the awnser for you.
what i did to bypass this was simple, I put in my vista cd ran it like i was going to install and formatted both drives and removed the partition from the drives and it worked

              hope this helps somebody.........

a bit strange behaviour. I am using ubuntu 12.04 on hp pavilion laptop with cinnamon, nemo, nautilus (but he behaviour is showed in other cases). I have external usb hdd and a crypted partition (luks format) on internal hd. when I unmount external hdds it doesn't show any message like 'it is now safe to remove drive' and sometimes says 'failed to unmount'. when I unmount the crypted partition it says always 'failed to unmount'. however hdds and crypted partition are always unmounted. it seems that the system fails to check and close applications and processes related to hdds and partition. I have another normal xfs backup partition on internal hd, which doesn't show such problems in unmounting.
