It's fine, as in, it won't break anything. My observations are:
  • 30GB for Windows 7 and installed programs is pretty tight. It will work fine as long as you do not exceed about 85% capacity. Windows needs room to breath in normal usage.
  • The dark blue partitions are Primary Partitions. You can have a maximum of 4 of these. That light blue partition with the green box around it is an Extended Partition and S: is a Logical Drive. This is good. You do not want to create dynamic disks! (unless you mean to) You can have many more than 4 partitions inside an Extended Partition as Logical Drives. For that matter it may make more sense to use the 99GB space as the Extended Partition.
  • Finally, it is a PC convention to use Drive letters A and B for floppy disk drives. Now I know that floppy disks are a fading memory and in most cases you will have no issues with naming a Hard Disk partition A or B, but it can cause a problem with older programs that assume that A or B must be a floppy. If you have no older programs and will never use one then you don't need to worry about this.

You may need to extend space into C. Now or later. It is more of a preference than a rule.

If you intend to install Linux (or any other OS) you may only be able to install it into a Primary partition. Sorry, I do not have any experience with dual boot Linux installations. I know that Windows 7 can be installed to a Logical partition, I just don't know about Linux.

That is why I suggested making your small 19GB S partition the Primary, and your large 99GB partition the Extended/Logical one.

Maybe someone else will come along that has more experience with Linux.

Was there another question I missed?

Download and install Partition Wizard Home Edition (free).

Also download the ISO image for Partition Wizard standalone boot CD and burn it to CD, which can do everything the installed PW version can do as well as work on the Windows C-partition itself (which the installed version cannot do while Windows is booted and running).

PW can change logical to primary and primary to logical, as long as the resulting partition arrangement is consistent and meets several requirements:

(1) There can be no more than four primary partitions on a "basic" disk.

(2) In order to support one or more logical partitions on a drive, one of the four possible primary partitions must be conceptually reassigned to instead be called the "extended partition". As such, it is no longer one of the four maximum true primary partitions available for your use, as it is now strictly used to hold the one or more logical partitions sub-defined inside of it. That means there are now only three true primary partitions on the drive available for your use. The re-allocation of that primary partition to become an "extended partition" is done by Partition Wizard as necessary. It is also un-done by Partition Wizard if you delete all logical partitions thus making all of the space now available again for use as a true primary partition, if you want. It might be necessary to delete the entire "extended partition" once you delete all the logical partitions inside of it (thus returning all that total space to "primary unallocated", and then "create partition" type primary, to get it back as a true fourth primary partition for your use.

(3) if you have one or more logical partitions inside that "extended partition", they must be consecutive with no primary partition separating them. They can, however, have "logical unallocated" space between them which theoretically can be used to define more logical partitions.

(4) There is no limit to the number of logical partitions which can be sub-defined inside of a single "extended partition". There can only be one "extended partition" on a drive, but there can be any number of logical partitions sub-defined within that one "extended partition".

You can do anything you want when booted to the standalone boot CD.

So if you boot to the standalone PW CD you can convert logical to primary or vice versa, or do anything else PW can do. This is generally considered the prudent, safer way to do anything with PW.

Or, if your partitions of concern don't involve the C-partition where Windows lives, you can do the same thing through the installed program under Windows 7. Again, you can use the installed program to do anything not involving the C-partition.
