HP Stream 7-Windows 10 doesn't boot, I can't recovery 8.1 because can't boot from USB-HELP please!!

[Ruggero1912]

Ok, thank you very very much! 

I will update you when I finish 😄

The tablet is starting up again with Windows 8.1 with Bing! I'm so glad 🙂

Thanks a lot again!

I'm glad that worked for you as well.

A tablet is not the best idea for testing a preview version of Windows. I use Hyper-V on a desktop repurposed as a server which makes it easier to work with new products.

The problem you have, you did not make a recovery USB stick or DVD for your machine so there is nothing to roll back to.

if the stick will not boot, it may be corrupt

Thanks for the rescue steps, I made all (but in my case restore option available was only for Windows 10) but I got stucked amazingly in the last TPM Keys blue box question because I have no USB keyboard or mouse. I purchased a tablet keyboard (microusb) and a USB-microusb adapted mouse without success so far :'( Should I purchase a regular USB keyboard? 

[travmaximilian]

Yes, you will need to have just a regular USB mouse and keyboard, even with just the keyboard you'll be fine. Borrow one from another computer or from your friends, it isn't really necessary to buy one.

It is recommended that you reconfigure the TPM, otherwise if you don't, this could cause errors for softwares that rely on the TPM chip for security (such as BitLocker).

Well, all worked fine until tho operating system option. There the only OS to roll back to is windows 10.. am I doing something wrong? Also I did not see any "recovery" option in boot from efi file step. Should it say recovery literary or should sya the usb stick name?..  could I just identify the usb that I need.

I will try again with another USB stick..maibe this one is "special".

Please advise.

Assuming you have made a copy of the recovery partition, the USB will be labeled Recovery. If not, it will show whatever volume name it has. Remember that UEFI boot requires a FAT32 FS, and yes, you will be able to tell whether the drive is internal or USB, it will say there in the directory path just underneathe the volume name (eg. Drive from USB will contain /USB path).

@fotogruia in my case the os shown was also windows 10 and as I wrote it worked fine. Good luck!
