Hi
After I go through Welcome (OOBE) and it goes to the Desktop, the first message is 'C:\Windows\system32\systemprofile\Desktop refers to a location that is unavailable. ...'

I should mention that the system I ran your app on is Win 7 64-bit Ultimate. Would this make any difference when installing Win 7 32-bit to a USB HDD?


The problem you mentioned is nothing to do with the PWBoot, it might be a user profile problem.
I think this will be useful: http://answers.micro...41-3aee83d69daa

Also, there are no differences between host system(in which you ran the PWBoot application), the output should be identical.

Testing OS: Windows 7 Thin PC
Install method: Physical drive

Just reporting...

Running patch on external hard drive with Win 7 SP1 x64 installed from both Win 7 SP1 x64 host and Win7PE_SE x86 PE result in expected, issue free outcome. USB hard drive boots normally and all OS/programs/internet/devices etc. work exactly as on the original installation which I backed up with Acronis and restored to USB-HDD.

Thanks again for great utility.

:cheers:

Nice,

can you post changelog? Any chances to unpatch option in incoming releases?

Isn't the change log is listed on first post? :unsure:
Unpatch option still not in the consideration because the patch doesn't affect the normal boot, therefore unpatching makes no difference.

Changelog - oops :) thnx, unpatch would be useful due the not working usb boot, ex. after sp1 install i couldn't boot from usb (before it was possible), and i couldnt patch system because it was already patched

right now im having another issue - usb boot works great with my notebook, but when plugging hdd via usb to another one i get 07b bsod :( safe mode fails with disk.sys file loading. any solution to this problem? I supose it is same error which occurs while changing windows hardware configuration.

redgards :)

For the Service Pack, if SP update does change anything sensitive to USB boot, the PWBoot will detect and report as "Unpatched" (This is by design, but not fully tested).

For the BSoD issue,
I guess there might be some problems with the USB port or hub (Is there any other devices connected to USB during boot time?)

No, only USB HDD. I've even unplugged internal SSD from not booting notebook :(

edit:

i've done some research and it is said that running system recovery on another computer should fix this issue. I supose it will also rewrite USB boot config

Based on your situation, it is USB port related problem (or anything else? :dubbio: ) on that notebook computer.
Your external HDD boots fine mean there are no problems with the Windows installation, no repair is needed.

Each time it fails i need to apply set_7_usb_boot.cmd from second hdd (internal) and it boots fine. THere are some problems with USB 3.0 hub - devices is being mounted and unmounted in some time. USB 2.0, which has connected USB-HDD works great for all devices

Thanks for help :)

Hmm - I don't understand what I am doing wrong! I tried RTM and SP1 x86 Win 7 three times now - also Starter and Pro. Result is same for all. Appears to install and get to Desktop OK, but after reboot I get the same error and no Explorer or Desktop or wallpaper. Presumably you can reboot as many times as you like and it always boots fine (on real h/w)?

Do you mean that you need to apply "set_7_usb_boot.cmd" before boot by every time?
Maybe you can try to use another USB cable for test whether the devices still being mounted and dismounted again.

How about the install.wim from another Windows installation ISO? :dubbio:

yes, i did. Right now i don't need it. Only in case of crash. These devices which are mounted and dismounted are mouse and flash stick with no any extra cable

Yes, boots repeatedly from real h/w and once booted is indistinguishable from host installation; everything works normally.

The only difference I see with your setup is x86 install, mine is x64 and not a fresh install; I restored a backup image of the host install to USB so everything is setup the way I want. The WD 300GB USB-HDD is setup with two NTFS partitions, Win 7 being restored to first, active on USB.

An existing installation would not got through the OOBE (i.e. sysprep) and would have existing user profiles...

I use Universal Restore, can't say for sure what the differences are but booting to dissimilar h/w is not an issue. Personally, I can't see doing this any other way than using an image restore, too much time and too many hassles installing direct to USB.

Hi,

Is it possible to make available a non-compressed executable?

My antivirus (AVG) goes crazy with this file and doesn't even allow to execute. Tried disabling the AV but it was stubborn, eventually uninstalled AVG to test pwboot.exe but I'm sure many other folks out there will not like to see this warning message.

I'm starting to test out the tool, so far I'm liking it.

:cheers:

I am not aware of sensitivity of the UPX-ed executable to anti-virus program. (I don't use them)
I had disabled UPX on compiling process.

Here you go:
PWBoot 3.0.2 (No-UPX).exe (1.61MB)

Umm, you don't need PWBoot for Windows 8. It has a bootable USB stack. It should run fine off a external USB device. Also, Windows 8 can boot off literally any machine compared to Windows 7 because it has more drivers built-in ready for the job. You can't exactly boot Windows 7 from USB on Intel and then switch to AMD out of nowhere, it'll fail boot-up or BSOD.

Also, certain USB hubs just aren't fast enough or simply won't work with Windows 7 booting from USB. Windows 8 gets the bootable USB stack from Windows Embedded Standard 7, which is a fully componentized release of Windows 7, it's the same Windows 7 but you can take parts out or put your own parts in, for example, the option to use a bootable USB stack instead of a normal USB stack. It's a supported scenario out-of-the-box, unlike Windows 7.

Windows 8. It has a bootable USB stack.

Thanks, that's greate news.
Let's read from install.wim.
[HKEY_LOCAL_MACHINE\8\ControlSet001\Control]

"BootDriverFlags"=dword:0000001c

 

[HKEY_LOCAL_MACHINE\8\ControlSet001\Control\PnP]

"PollBootPartitionTimeout"=dword:00007530

 

 

[HKEY_LOCAL_MACHINE\8\ControlSet001\Services\usbhub]

"Start"=dword:00000003

"BootFlags"=dword:00000004

 

[HKEY_LOCAL_MACHINE\8\ControlSet001\Services\usbehci]

"Start"=dword:00000003

"BootFlags"=dword:00000004

 

[HKEY_LOCAL_MACHINE\8\ControlSet001\Services\USBSTOR]

"Start"=dword:00000003

"BootFlags"=dword:00000014

 

[HKEY_LOCAL_MACHINE\8\ControlSet001\Services\USBHUB3]

"Start"=dword:00000003

"BootFlags"=dword:00000010

 

[HKEY_LOCAL_MACHINE\8\ControlSet001\Services\USBXHCI]

"Start"=dword:00000003

"BootFlags"=dword:00000010
Yes, boot USB stack is enabled by default. And USB 3.0 drivers are available too.



Also, certain USB hubs just aren't fast enough or simply won't work with Windows 7 booting from USB. Windows 8 gets the bootable USB stack from Windows Embedded Standard 7

This explains different behaviour at Windows 7 USB stack.
