Windows 10: Trying to Downgrade to Win 8 Using EasyBCD, BSOD occurs, 0x000000f.

Hello,
Just as the Title says, I am trying to Downgrade my Lenovo Yoga 300 with a Windows 8 ISO using EasyBCD, Since i dont have a flash drive, I could not do it and had to resort on EasyBCD, I forgot to add some files to the partition and i made the Installer default, and Cant boot, Solution please?
I at least want to boot into Windows 10 back.. Anyway thanks.
(i do not wanna buy a flash drive)
I have the Yoga 300-11iby, It is the 500GB hard drive model, My problem is, I have win 10 working, but i mistakenly made Windows 8 installer (which is broken) the default, and when i click F9 to "Choose another Operating System" It gets me back to the same Win 8 Error
and YES, Windows 10 Works, But BCD boots Windows 8 as default and does not give me an option to choose win10, when i click F9 to change systems it gets me back to the BSOD

:)

Trying to resolve a dxgmms2.sys bsod that occurs while playing Dungeons and Dragons Online.

Yes, Dungeons and Dragons Online.

Two things were updated before it started. An nVidia card driver and a Windows 10 update. I had the 3 bsods inside of 2 hours while trying to play DDO. The file specified seems to indicate DX12, so I came here to look into it further. Tried to update
DX12 even though it was updated, to be sure, to replace any bad files, but the site says those updates aren't available separate from Windows 10 updates.

 

If you upgraded to Win 10 from Win 8 within the last 10 days you could have reverted to Win 8. That is supported. 'Go back to previous version'.

I assume you upgraded to Win 10 more than 10 days ago.

You cannot use a Win 8 iso to revert to Win 8 from Win 10 and keep programs and data on 'C:'. You would need to do a clean install of Win 8.

If you need to repair the boot process to try to get Win 10 working again, you can try getting Macrium Reflect (free)'s boot medium, and using its Fix Boot utility.

(You can read about that by searching for it- it's written up in their Knowledge Base- not hard to find).
