Windows 7: Change boot partition size

Change boot partition size

I am trying to get my computer set up to dual boot Win 7 and linux (Slackware). My computer says that it's using BIOS, but when I use the "setup" command on the linux install, I get a message saying that computer is set up with EFI. I have chased down all sorts of info on how to deal with this. The last thing I was trying to do was use these instructions to change over to EFI.

In the diskpart procedure, the boot partition example (Primary 1) has 350 MB. My computer has 199 MB and I tried a few different combinations of sizes to get the EFI and msr partitions, but I didn't know what to put and each combo I tried resulted in an error. How do I expand the boot partition on my computer to at least 228 MB? I have gparted software and tried just expanding the boot partition, but the software gave me an error about trying to move the C: drive, which was on the next partition, saying I may damage it. To be clear, I would like to know either the right sizes for EFI and msr ("System") partitions for for my existing partition of 199 MB or some way to enlarge the partition to accommodate the minimum I need for the two partitions.

Change primary partition size?
Hey all! I was stupid enough while back to make my main partition (C: ) where I installed windows only 50gb big. What I wonder is, is it possible to decrease the second partition in size and move that extra size to the main partition without damaging data on both partitions? If so, what program...
