  Failed to run System api 0x00000015002E000
Posted by: reijken01 - 10-28-2015, 06:57 PM - Forum: WinToUSB - Replies (1)

I get the following message when starting WinToUSB 2.4:Failed to run System api 0x00000015002E0000

After the message the application seems to run fine but when creating a Windows 10 on an USB then during formatting the USB a BSOD occurs

WinToUSB runs on Windows Vista Ultimate 64x English (4GB memory, enough Diskspace on SATA disks)

The log:

Sad Trying to install W7/W10 fails due to an apparent existing AV or missing legacy mode
Posted by: MOS6510 - 10-22-2015, 04:54 PM - Forum: WinToUSB - Replies (1)

Good morning,

for a few days now, I try to install either Windows7 or Windows10 in legacy mode to a 64G Toshiba usb stick via USB3, all done from within Virtualbox5 running a Win10 VM.

The first time I did so - using an ISO of Win7 x86 - everything worked flawless and I was able to boot the usb stick on my real machines.

Trying to create a working device after that however always failed by various error messages that either tell to turn off the AV software (which doesn't exist, Windows Defender is completely turned off during the process) OR that certain files from the WIM files couldn't be copied over OR also having only VHD creation as an option to choose from.

Eventually, the typical Windows FS hierarchy with it's directories and files exist but necessary files for a proper boot do not.
To choose partitions does not work either as only one is shown unless I try to create a USB from the apparent existing "HDD" install that exists in Virtualbox but again, this will also fail due to missing boot files.

So my question is, what can I do to make things working again?
To use a computer with native WinNT install is not an option as I know noone myself around me who has a computer that runs Windows.

Kind regards,

  Installing .net on a WinToUSB Windows 7 SP1 64 system
Posted by: ttpatricio - 10-15-2015, 10:07 AM - Forum: WinToUSB - Replies (1)

I have successfully installed the Windows 7 SP1 64 system on my pendrive (Sandisk ultrafit 3.0 16gb, also a Samsung Evo 16gb microsd gives the same error). Everything is working except that i cannot install WIndows .net. I have tried the offline installer for the 4.0, 4.5 and 4.6, All of them fail on the end, saying "User canceled installation". It is the same situation on W7 ultimate and home editions.
Anyone has any idea how i can install it?

Also, totally unrelated: I think it would be useful if we could use WinToUSB to install windows on an internal hard drive/partition.

For reason I can't explain in brief, I have to update BIOS of a notebook. Is it safe to do this on a WinToUSB drive?

Thank you

  Usable memory only 1.6G?
Posted by: newnews - 10-02-2015, 02:41 PM - Forum: WinToUSB - Replies (3)

Installed W10 32-bit on USB3 stick. All goes well. However, in the system property, It says "Installed Memory 16GB(usable 1.6G)". Why there is 1.6GB limit? It should be about 3.x GB for 32-bit system.

  How fast would a usb 2.0 port run windows 7?
Posted by: jojosbizarre - 09-27-2015, 12:47 AM - Forum: WinToUSB - Replies (1)

Could I do things normally on a usb 2.0 port assuming I was on a fast/good computer? how slow would it run? I don't need a 3.0 flash drive do I? I only have 2.0 usb port...

I got a 16 gb flash for 5 dollars, doesn't it seem bad to set the memory requirement at 16gb? i mean 16gb should be enough for windows 7 and a few gb left over right? a 16gb stick only has 14.5 memory so it's certainly not enough

if i used the computer for an hour and a half each day on a windows 7 flash drive, how many years would the flash drive last? i know flash drives have a limited number of write cycles etc, some sites say it won't last long, but i think they should last several years because they have so many cycles

Star W2U-beta -> feedback
Posted by: Ratte - 09-19-2015, 08:20 AM - Forum: WinToUSB - Replies (1)


Nice to see a new beta-version (2.4).

Can we support developing?

What features are new or have been changed?
What should we test and what kind of feedback information is required?
