I bought a new HP Pavilion DV7-6199US. In the past on all my computers I have always used Ubuntu primarily and I keep a version of Windows in case I need something that I can't do easily in Linux. I have always just re-sized the main Windows partition to leave enough space for Linux to run with no problems. I would leave the remaining space for Linux on the disk with no partition or anything, just unused space. Then I would run Ubuntu's installer and tell it to use the unused space. Never a problem, Ubuntu would create partitions there however it wanted to.
This time I did all this, but when I resized the partition in Windows the remaining space was labelled unusable by Linux and Windows. So I said OK no problem I booted Ubuntu 11.10 from USB and I just deleted the whole Windows partition and created a 492 GB partition to install Windows on again.
After doing this the Disk Management Utility in Ubuntu said the following error: "Warning: The partition is misaligned by 3072 bytes. This may result in very poor performance. Repartitioning is suggested." Do I keep going? Is this just a screwy error that I can ignore? I can't handle bad performance issues.
I'm not very experienced with the command line so GUI-only unless you can really be patient with me, please.
