I uninstalled Ubuntu via "How-to-Geek" instructions, but upon completion my boot menu is gone and I can only boot the simple "grub" command line. Booting to my Live USB with Ubuntu works though (I am using now) but when I go to reinstall I no longer have the option to make a new partition to dual boot windows too. I must somehow make a new manual partition if I want to be able to dual boot to windows.
A little more detail: I just figured out that I can still load my old windows desktop if I directly select to boot from it from the Bios menu, so I know everything still works fine. So the issue is just that Ubuntu is not seeing my windows partition and is only giving me the option of writing over the whole thing.
