Reinstalling Grub

I recommend avoiding dual booting if one or more of your systems is Windows, because Windows does not play nice with other operating systems. But if Windows messed up your booting software (Grub) this is how to fix it.

RIP Ubuntu. Ubuntu was great. For years, I kept trying to get my own Linux box up and running, initially so I could relive the halcyon days of UNIX and later so I could avoid Windows. But every time I tried to get Linux working some key thing would not be configurable or would not work. Well, I'…
When it comes to ease of use, there is no difference between a computer with Windows and a computer with Linux, assuming both systems are installed properly. That there is a meaningful difference is a myth perpetuated by Windows fanboys or individuals who have outdated experience with Linux. Also…

Depending on what Winduhs is used for, I would recommend running Winduhs within VirtualBox (or similar) rather than dual-booting. "WINE" is another option. There is one huge caveat: some malware like SecuROM which prevent the rightful owner of software from running that software (accusing the owner of being a seafaring plunderer and murderer) may rear its ugly head and prevent you from using the software you wanted to use. In such a situation you may be forced to run the GNU/Linux system within Winduhs instead (*gag*).

SecuROM and other have simply put me off of buying games; when I buy a game I have no idea whether it has such malware or not and I've had more than enough of being hassled every time I want to return a game which refuses to run. Unfortunately that is also bad news for the game publishers who don't use such malware; since I can't tell their product apart from the nonfunctional products, I simply don't buy games. So I'm stuck with free games - but they're getting better. :)

Grub is awful.Give me lilo back.
Installed Windows 7 the other day,didnt unplug the Linux disk,and lo and behold,Windows is still removing the boot flag of every other OS,some things never change.
Sometimes just switching the boot flag back on is enough,sometimes you need to go through the above shown process,sometimes you need to reinstall grub,if you can boot into the system,that is.

The better way to multiple boot is to run a Macintosh with Parallels or Vmware Fusion. Provided that one has enough memory, one can run Windows XP and several Linux operating systems at the same time, using a feature known as virtual machines. Of course, Leopard is also running so there is a certain operational penalty, but one can't have ones' cake and eat it too.
