Gents, First of all thanks for reading this post. I'm quite new here and have read and learned tons of great stuff about Modding Bios, Win 7, etc. I have an Asus P5N32-E SLI that I'm contemplating modifying the Bios so I can install an OEM version of Win7 64. I found my Bios already modded by P4Spooky (Thx) here: Code: http://forums.mydigitallife.net/posts/65692?highlight=P5N32-E#post65692 But I have a couple questions I'd like answered before I decide what to do (I know I could use a Loader instead, but that has potential issues long term.). If I use a modded Bios does my legit WinXP Pro Hard Drive just ignore the SLIC 2.1 changes and continue on as normal? (I expect it does.) I contemplating migrating to Win 7 but not certain I can go there in one step. I install OSes on separate drives as I'm not a fan of Dual Booting. (I use a couple of "Sliders" and plug in various drives for data / different OSes, specific apps, etc. I've also read some posts where people say you need to use "switches" when installing modified Bios => other posts that say install the modded Bios as you normally would (I have about different 3 options to do this on this Motherboard.) Is there a definitive answer I missed somewhere? Oh and another item. (Not really related => sorry if it's out of line...) I really want to back up Win7 once I get the image installed with various Apps. I haven't found any officially supported back up suites. True Image 11 is in the same position as Ghost 14 (my preferred) => both are supposed to work (according to folks on the Web) but their not officially supporting Win7 (yet) and they give error notifications at times. Acronis True Image Home 2010 and Acronis Backup & Recovery 10 are supposed to support Win7 but they aren't out yet in those versions (as far as I know). I know a standard install of Win7 has 2 partitions but most back up programs I've used only go for the "C". (Some don't even normally "see" small hidden partitions.) Do you know of any package that officially supports Win7? Thanks for your input. Sorry if this is too Newbie.
