Create new partition table

I am trying to install Ubuntu on dual boot with Windows 7. I already created a partition, but for some reason Ubuntu does not give me the option to install along side Windows 7. So I thought let's install Ubuntu in that partition manually. Only thing is that Ubuntu is not detecting my partitions in the hard drive. What do I do? It says that I can create a new partition table, and all other partitions will be deleted. Will I lose my stuff like that?

Hold the phone!

Did this new partition happen to be the 5th? Ubuntu require a primary partition or logical inside and extended partition. Some manufacturers put windows on 4 primary partitions and that is the maximum allowed by a system. If that is the case in your system then you need to either delete one of the partitions or convert it to a non-primary. For example, if one of the partitions is for diagnostic tools then you can probably get away with deleting it. To be safe make a back-up image and then go to a discussion group in your vendors site for advice on what to ditch safely.
 
As Ubuntu is not detecting partitions I don't think it can be a question of too many partitions (and I'm pretty sure that gparted won't work). My best guess would be that your Windows disk is a dynamic disk, not a basic one, and that you have created a volume on it rather than a partition.

How did you create the partition?
Did you format the partition? If so, which file system did you use?
Have you checked in Windows Disk Management that the disk is a basic disk?

Whatever you do, don't accept the suggestion to create a new partition table; that will, effectively, wipe your disk clean.
 
Well, the OP does say that Ubuntu doesn't detect his partitions and that Ubuntu offers to create a new partition table. That sounds to me as if it is not reading the partition table at all. This would, of course, happen with a dynamic disk, hence my suggestion that this is a possibility.

I think it's reasonable to suggest this as something to check, if only to eliminate it.
