Failing to boot Windows on an MSI PC, asking to select among two partitions after hitting F11 and getting an error message.

I can't get Windows 10 to install on my new PC.

I can get into the bios to set up the requirements for Windows 10, (UEFI as boot mood and boot priority- UEFI USB (Sandisk) and then the UEFI Hard Disk), but when I go to shut down and reboot my computer, I hit F11 and am asked to select boot media.

Option 1 says- UEFI Sandisk Partition 1, when I select it, the arsenal logo disapears and then immediately reappears with the exact same screen. It constantly loops.

Option 2 says- UEFI Sandisk Partition 2, and when selected I get an error message that says "b1initializelibrary failed 0xc00000bb"

Option 3 says- SET UP and brings me back into the Bios

Does anyone know what to do?

Hailey, I hope that you do not mind that I reply to your inquiry using this less than formal persiflage?                                          Initially, I connote that you mention that you have partitions within your computerized device.  I too employ a partition within my own computerized device, i.e., Windows7-Pro, and Windows10-Professional operating systems.  Much the same as yourself, I simply wanted to assure myself that when I upgraded my operating system, e.g., my O/S, that I would not be left falling without a back-up parachute operating system; not that I haven't a great deal of trust and faith in Microsoft Corporation's product lines as a pedestrian end-user with some 45 or 50 years of exposure to Microsoft Corporation's product lines, as I do have.  Nonetheless, the Windows10 line-up of suites, I have observed have a peculiar peckadillo, the Windows10-Suite of product software does not play well with elder Windows operating systems that occupy the same CPU cabinet; while, the Windows10-Suites do work quite well on an infra-network and/or an internet arrangement of computers; Baudot/ASCII communication shortshifts notwithstanding; that which actually speaks highly of Windows10-Suites' inclusive and adaptive learning capabilities, indeed!                     Not having first-hand exposure to your specific computerized device; I venture to suggest to you; "Is it possible that your computerized device has some loose, dirty, or non-conducting interconnecting connections, pins, e.g., legs?  If your computerized device remains under warranty, have the vender and/or OEM manufacturer look it over and require them to fix and repair it, at their expense; in-fact, your device's warranty may require the vender/OEM manufacturer to provide to you a temporary replacement or stand-by computer while yours is being repaired, or operatively replaced with a certified, working computer, of equal and/or greater and better operating capabilities.                 ẞecond scenario: You are quite certain that your electronic device continues too have enough space left on its integral hard-drive to employ/install the additional metrics that you obviously intend to make use of; Yes?       Consider, a greater capacity integral hard-drive or even, the installation of an additional integral hard-drive.  Perhaps, an external drive, or an external USB drive could be what the doctor ordered.                             

Perhaps, the copy of your electrobic device's BIOS is not a current one and therefor, sinply needs updating off of a computerized device's currently updated Windows BIOS.  An other pozsibility is that, an this is what my device's present foible is; your computerized device simply needs a currently updated copy of your operating system's (O/S's) image to be loaded into it; Yes?                       

Hailey, all of these possiblities, these potentialities, each stands on its own merit, should and/or will remedy your electronics device's problematic circumstance; just REMEMBER, start with the most logical and Simplest fix for your electronic device's software and/or hardware's repair requirements.                     I hope that these food-for-thought, technical suggestions speed you along your expedited repair resolution(s) way, so that you will be able to competently and safely merge into today's bustling traffic on the information highway!            POSTED: 00:30 EDT (USA),         12 MAR 2020.

Is it possible to create your flash drive using another Windows PC? While the steps you tried would have created the installer, it's best the ISO file was created through the usual means.

Also, does the flash drive include all of the needed files? Please send a screenshot of its contents so I can check.

Hello,

I'm your Windows expert for today. Let's work together and arrive at a solution!

Please answer the following questions so we have a better idea of what might be happening:

1. Is the PC custom-built? If so, what is the manufacturer of the motherboard?
2. How did you create your Windows 10 installer? Did you use the Media Creation Tool?
3. Do you have Secure Boot disabled in BIOS, if such an option is there?

Any information you provide will greatly help us in resolving this concern.

Hope to hear from you soon.

Here is the first section of it's contents. Let me know if you want more screenshots. 

Thank you!!

1. Yes, MSI. It's a B450.
2. I paid for Windows 10 and downloaded an ISO file on my mac. I then put it on a USB drive. I formatted the USB drive using this article (https://www.freecodecamp.org/news/how-make-a-windows-10-usb-using-your-mac-build-a-bootable-iso-from-your-macs-terminal/) 
3. Secure Boot is disabled.
