If you can boot the system & access the BIOS, you do not need the "reset pins". All you need to do is properly configure the BIOS settings manually, or load the defaults.

In the future, help yourself by keeping copies of all your personal files. If you need to add additional hard drives then do so.

In my opinion the most reliable backup method is to save the files to DVDR. If you wait until you have 1TB of data it may take quite a while to burn that much data.

The amount of effort you should put into keeping copies of personal files is inversely proportional to the importance of the files. Irreplaceable files like photos or manuscripts should be treated with even more card. Multiple copies including off site storage.

Why were you trying to boot from a flash drive to start with? Was there a problem with your Windows installation?

It is hard to stress enough the importance of maintaining backups of important data. Hard drives fail and data can be lost from a variety of other causes as well, some of which you have no control over. Having only one copy of important data is like walking a tightrope with no safety net. Sooner or later you will fall.

"Where Are The Bios Reset Pins?"

For the benefit of those who actually need to know where the pins are, without downloading the manual or wading through "answers" from those who have no idea
where the pins are:

RTCRST pins to clear the nvram are located a couple of inches below the main power connector. "The NVRAM will be cleared when the jumper is closed... To properly clear; AC power must be applied (not necessarily turned on) to the system for about 10 seconds while the jumper is closed."

Or just download the manual:

The information in #5 above is incorrect. If power is left on to the motherboard the CMOS will not be cleared. You must perform the operation with power to the motherboard interrupted.

If the motherboard is running at the time you try clearing, or you attempt to start the board with the jumper in the clear position you will damage the board.

Clearing the CMOS resets the values to defaults which will make the time and date wrong and may affect other setting that you may wish to change. One that comes to mind is called legacy USB support.

Also, the pins to clear the CMOS may be located wherever the board manufacturer sees fit to place them but usually are next to the BIOS chip. They are always marked somehow. Usually with clrcmos. They may consist of two or three pins. When two pins are used no jumper is present. When three pins are used a jumper is placed accross pins 1&2 which is the run position. Cllearing requires your move the jumper to pins 2&3 momentarily while power to the board is off.
