Hi Vlad, thanks for your question. I'm Graeme, a Microsoft Community expert and fellow user.
It sounds like your USB drive is being unmounted midway through Windows loading, or the USB drivers haven't installed correctly. Either way, I've found a couple of possible solutions in the below Apple forums thread. I'll copy one of them below:
'After the BSOD mac will restart to 'Start Windows Normally' screen hit Enter To Start Windows Normally
Go to device manager (Start and type devmgmt.msc and hit enter ) and uninstall 'unknown device' under 'Universal Serial Bus Controllers' Tick 'Delete the Driver Software for this device.'
Now go to your Bootcamp folder i.e. BOOTCAMP_5.1.5621 or BOOTCAMP_5.1.5640 and goto Bootcamp > Drivers > Intel
Now run the file IntelxHCISetup.exe. It will show you the intel usb3.0 setup assistant. do not install or cancel the setup as it will delete the temporary folder in temp
Now goto Start and type taskmgr.exe and hit enter. It will open up Task Manager.
In that you have to select Intel Installation Framework and type Shift + fn + f10 (While typing don't press the + key coz its a combination :slightly_smiling: ) to open right click menu (by default you cannot get a right click menu unless you finish installing bootcamp fully)
Select 'Go To Process', and again press the Shift + fn + f10 key combination to bring up the right click menu
And then select Open File Location, Now copy the contents of the folder to a new location i.e. by creating a new folder in the desktop or any other location
After copying the contents of the folder to a new location go to Device manager and right click the Unknown Device and press the Right click key combination Shift + fn + f10 and select Update Driver Software > Browse my computer for driver software and browse for the folder that you created in Step 8 and click next. It will detect the driver and installs it automatically'

Please let me know how you go and if this doesn't work, I'll see what else we can try! Thanks!

Editor’s Note: Previously, we published a post by Daniel Pataki on How To Install Windows on Mac when all else fails. Alvaro is one of the many readers who left a comment on that thread. Below is his version on how to get Windows Boot Camp, and thus, Windows, on your Mac. I have a late 2009 27. Sep 24, 2018 Here's how you can clean install macOS Mojave final version without creating a USB installer drive. This requires an internet connection.
