Tri-Boot Help: Windows 7 / Snow Leopard / Ubuntu
First, here's my hardware profile:
Motherboard: ASUS P7H55-M PRO
CPU: Intel i3 530 @ 2.93 GHz
HDD: Samsung HD103SJ 1TB @ 7200 RPM
Graphics: EVGA with nVidia GeForce 9800 GTX+ (512MB DDR3)
I first installed Windows 7 successfully after making 3 NTFS partitions on my samsung HDD: 302 GB, 302 GB, 326 GB. Windows was installed on the first partition. After creating my USB stick using the lifehacker preparation guide, plugging it in, and changing the SATA configuration from IDE to AHCI in my BIOS, i got as far as the Mac installation screen where i am prompted to hit any key if i want to have installation options as a timer winds down. Naturally, i do and am brought to where i get to choose on which volume i want to install snow leopard. There are 5 volumes listed:
osx86, System reserved, Windows NTFS, Windows NTFS, Windows NTFS
osx86 is my flash drive, and under the assumption that the volumes were listed in increasing partition number, i highlight and select the middle of the three NTFS partitions (since i figured the NTFS partition on the left contained my Windows 7 OS). I then received the following error
Worried, I wanted to check that my Windows 7 installation was fine. So I restarted my computer, reverted my BIOS settings from AHCI to IDE, and luckily windows loaded perfectly. I was thinking there had to be something wrong with the HDD format. A bit annoyed, I decided to move ahead with my ubuntu (64-bit 10.04 server) installation. I got as far as the language selection page, but i don't think the ubuntu installation software couldn't recognize my wireless keyboard and mouse (which i thought was a bit strange because i could edit my BIOS with the same wireless keyboard without any driver installation).
BOOTMGR is missing
Press Ctlr+Alt+Del to restart
So thus far, I am coming across 4 main issues, the last one being a bit off-topic for this forum, but I'm hoping some linux-savvy hackint0sh users can help me kill four birds with a few stones:
1.) What's the deal with the "BOOTMGR is missing" error, and how can i get around it? I've googled for help but can only find windows-specific problems, but nothing related to my hackint0sh set-up
2.) I find it very annoying to have to always go into my BIOS and toggle the SATA configuration between IDE and AHCI in order to avoid a Windows 7 crash. Presuming I can successfully get all three OSs on my HDD, is there any recommended low-level bootloader software I could install that runs before BIOS runs that would allow me to choose which operating systems of the three (and their associated OS-specific BIOS preferences)?
3.) I am worried that the format of my disk volumes is an issue. What are some recommending disk formatting utilities that would allow me to format any of my three partitions as NTFS, HFS+ (journaled), and Ext for my respective OSs? Again i've googled some stuff and can only find FAT-NTFS formating tools, a couple that support Ext, but nothing for HFS+.
4.) I'm thinking that the OS doesn't detect my wireless keyboard. If i can successfully install ubuntu on my third partition using a WIRED keyboard and mouse, does anyone know of any sites where I can download a linux driver for Microsoft Wireless Comfort Keyboard and Mouse 5000 so that i don't always have to plug and unplug my wired keyboard and mouse?
All and any help will be greatly appreciated!
