I have an Acer Aspire 5732Z that is currently dual booting W7 and Ubuntu. It is partitioned into 3 primary partitions and 1 extended one that contains 4 logical ones. I am completely sure that the extended partition and the W7 partition are necessary how they are. The other two primary partitions are called "SYSTEM RESERVED" and "PQService".
I have heard about being able to remove PQService, but it all seems rather confusing and overly risky, deleting the MBR and hoping that Windows can recover.
Is there a way I could safely merge the two extra partitions, or a safe way to delete PQService? I want to make another partition for a Mac OS X installation, but Gparted says that I already have the limit. I have also tried to resize the extended partition and add a logical one to it for Mac, but it contains all of the Ubuntu files, and is unumountable, I don't know how to do it in windows.
Note: I have Plenty of space on my drive, I just reached the partition limit.
Edit: I don't have a functioning cd/dvd drive :(
