Hello BNC,

You can do so from either one of those versions.

Thanks Brink

However I just got some info from a technet user which disagrees with your advice.

Check out http://www.winsupersite.com/win7/win7_skus_compare.asp

If this site is correct, I need Ultimate for VHD boot, however VHD Create/Attach works on all versions ??

It looks like I may have been mistaken on that. It does appear that you will need W7 Ultimate to boot from a VHD instead. I had thought that it would to with being able to create and attach a VHD in the Pro version as well. Sorry for the mistake.

Win 7 USB Boot

Hi,

I tried the tutorial method to clean, make two partitions on my Seagate 250GB HDD (ST3250310AS) in a Spire GigaPod III SATA-USB enclosure, then installed Win7 from the DVD (7100) onto the first partition. It gave me an error message saying that my computer would have boot problems with this configuration but did the installation on confirmation. It also creates the appropriate entries in the BCD (and adds a "Windows 7" entry ).

When I set boot from USB, the laptop displays the Starting Windows screen for a second, then a blue screen with errors momentarily, then reboots. This process keeps repeating on each reboot.

Can someone point out where I am going wrong ?

My laptop is a standard Dell Inspiron 1525 (T5800) with Vista HP SP1 preloaded, having 3 GB RAM, 250 GB HDD. I have created another partition in it other than the pre-configured ones (one for OS, one for recovery, one for OEM) and have installed Win 7 RC1 on this partition with a dual boot with Win Vista. This setup works fine, however all my USB boot experiments have failed till date.

Hi Sandy,

Unfortunately we really need the BCCode or Bug Check Code to be able to diagnose installation failure at that stage of the Windows Setup, If you able to provide the digits Ive highlighted Red then we can give you a more specific cause

0x0000123 (0x000000, 0x000000, 0x000000, 0x000000)

If your unable to view the BCCode before your system restarts can you upload the Minidump file located here: C:\Windows\Minidump\Minidump.dmp

Cheers

Thanks for the tip Steven. Unfortunately, I ran into problems with jaunty and grub. I had to clean the disk of existing software. I shall attempt th re-install in a while, I shall upload the minidump file then.

Virtual PC VHDs can boot too!

Well ,I'm not sure if I have read the whole thread carefully enough to not repeat something, but dmex states at his warning in the beginning of the tutorial , that you cannot boot a Virtual PC VHD, due to different HAL configuration (Pentium III) , so you will need to use VMWARE...

Well, I just booted one (VIRTUAL PC made) and I'm actually running it now... and if nobody else has posted it, I wanted to share it with the rest here.

Here's the case:

1. I'm running Windows 7 RC 7100.
2. I installed Virtual PC 2007 SP1.
3. I made a VHD and installed Windows 7 7600 on it.
4. I even installed a language pack from the ones leaked on the net.
5. Then I ran sysprep from within the virtual machine and shut down the virtual machine.
6. I added the VHD boot entry on my host OS in order to boot from my newly created VHD.
7. I added the command bcdedit /set {my_vhd_CLSID} detecthal yes
8. I restarted, selected my VHD boot option and here I am...fully operational.

Again, I apologize if someone else has already posted this, but I still saw the warning up there so I had to say it's been overcome.

Cheers

If you sysprep it, then that removes the HAL.

It's still "cleaner" to install it fresh then to use a virtual pc vhd.

Thanks, limneos.

Do you see any advantage of booting a 'Virtual PC .vhd',
versus having installed Win 7 'directly' into a newly created .vhd (as in the tutorial)?
(ie, No emulated NIC, faster running w/o emulation, no core-memory limits, etc.)

Thank you for the post.
Sounds interesting, since I have Win 7 installed both ways...

Well, I don't think there's an actual advantage, it's always better to use a clean installed OS, either in VHD or in any other medium

The thing is that, if you already have a Virtual PC VHD with which you've been working with, you can boot with it too.It's just good to know you can also boot this already setup OS.
