unallocated space not used Install alonside other operating system

Asked by pererik87 on 2010-10-06

unallocated space not used when selecting Install alonside other operating system.
I use 64 bit Maveric-rc. I have a 100MB windows partition and 150 GB unallocated space. When i click next Ubuntu wants to use the windows partition and leave the unallocated partition unused??

I know It's possible to do this by manual partitioning but should not ubuntu installer detect the unallocated space??

Im solving this by using gparted to increase the windows partition and then run the installer again to avoid dealing with the manual partitioning thing. I just don't want to put effort into learning how the installer advance partition thing works.

Sounds weird... Are you sure you don't already have 4 primary partitions on your hard drive?

i believe that installing alongside an existing operating system will result in ubuntu being installed in a formatted partion under windoze, so both opsys are sharing the same space.

you will want to install in the largest available free space. this allows dual booting and both opsys will reside in its own partition.

Maybe I forgot to ask you this question first: are you installing using Wubi?

Wubi will install Ubuntu partitions INSIDE Windows' partition. This way it's easy to remove Ubuntu and no need to change your partitions.

If you install using the CD though, Ubuntu will be installed in its own partition.

@Marcus There is no "install in the largest available free space" available. This is most definately the error of the installer. I assumed they merged install alongside and "install in the largest available free space", but its just removed.

Not using Wubi.....

did your format the free partition? that option disappears if you did.

if you DID format the partition, just go and delete the partition and try re-installing again.

"150 GB unallocated space"(Read description)

the option IS missing.

The option to install Ubuntu on largest available space is missing.

1) as francois said, you probably already have 4 primary partitions, or

2) if the "unallocated space" had NOT been formatted, then you probably have a bad download.

you can try downloading again and make sure to check the md5sum to ensure that you have a good copy. if you're unfamiliar with md5sums, do a search for "md5sum" to locate postings from marcobra, which gives instructions.

nope win7 only set up 3 partitions (root/backup/files) other i formated the last one to unallocated. I just resized the windows partition and installed alongside after that. I don't think you can blame a bad download for this anyway tho, then it would more likely crash then alter the menu.

unallocated is not a formatted state
Im not using wubi
This is not a problem for me, it is a feature request, to bring install on largest free space back
