Windows 7 – SP1, Multiple OS – Grub

A while ago I bought a Toshiba netbook which of course came with Windows 7 startup. Since I was going to be putting 4 OS’es on it (Windows, Ubuntu, Chromium and Meego), I was switching from the usual method of booting directly into Windows, into using Grub2. Of course now that the SP1 update has come out, it doesn’t install properly. This is the support page that the error pointed me to: http://windows.microsoft.com/en-US/windows7/windows-7-windows-server-2008-r2-service-pack-1-sp1-installation-error-0x800F0A12


Windows Disk Management Tool, used for setting active partition

Unfortunately, none of these options worked. It turns out, it is a simple fix (at least for me). In start menu, type “disk management” into the search, and click on “create and format hard disk partitions”. Right click on the partition that has Windows7 (likely the largest NTFS partition [don’t select the recovery partition] if you have a setup like mine) and click “Mark Partition as Active”. Then try to install SP1 again, and it should work fine.

A Frustrating Experience with Chromium OS

Recently I reinstalled my laptop and was hoping to add chromium onto my multiboot setup. I can get it working with the standard USB key approach that is recommended on all of the guides, however it seems like moving it to the hard drive is a completely different story. When it is compiled from source and put on the USB key, the partitioning scheme is GUID, and I use the older MBR scheme. It seems to me the only way to get it to work together is either to use a full GUID partioning setup or use some weird hybrid or mixed scheme. From what I’ve read on other blogs, it doesn’t seem particularly easy to get Windows to work with GUID. Also when you look at what gets created on the USB disk itself, its a mess of many partitions, and I’m not particularly fond of that. Perhaps this is an artifact of the GUID scheme since I’m not very familiar with it, so maybe someone can point me in a direction on how to proceed. For now I’ve given up and will wait and hope that Google will eventually release it in a way that is easy to add to MBR :S Until then I’ll just grudgingly use the USB version since I don’t want to dedicate my entire laptop hdd to using chromium os.

*note* I’ve also tried to the hexxeh version of chromium, but for some reason it won’t boot on my laptop, and I also prefer to be able to compile from source rather than using a pre-built image.
