How to Bootstrap cisco SD-WAN 850012x4qc

[saintvilk19]

Hello, I am trying to configure my SD-WAN 8500(17.06.04) router via bootstrap USB. However, I couldn't find any information online for specifically the 8000 series for placing the bootstrap file generated from vManage onto a USB correctly. 

I tried using the instructions Here and that didn't work. Could someone point me to the correct answer or let me know how to do such a thing?

Best way is to format the USB from a cisco router (in your lab)

1- Insert the USB - similar logs might come up

%USBFLASH-5-CHANGE: usbflash1 has been inserted!
%USBFLASH-4-FORMAT: usbflash1 contains unexpected values in partition table or boot sector.  Device needs formatting before use!

2- Format the USB in the router

router# format usbflash0: 
Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "usbflash1:". Continue? [confirm]
Format: Drive communication & 1st Sector Write OK...
Format: All system sectors written. OK...
Format: Total data sectors in formatted partition: 8191435
Format: Total data bytes in formatted partition: -100952576
Format: Operation completed successfully.
Format of usbflash1 complete

3- Save bootstrap config as ciscosdwan.cfg (case sensitive) and reload while the USB drive inserted. if that doesn't work, copy the file to bootflash and reload.
