Have you tried this:
Go into the BIOS
Go to Boot Menu
Boot Menu: Advance
Boot Priority: Hard Disk Drive First
Boot to Removable Devices Disable
Boot to Network Disable
Boot to Optical Device Disable
USB Boot Disable
Boot USB Device First Disable
USB Mass Storage Auto
Make sure to set the drives which has the OS installed on the 1st boot priority.
Let me know how it goes.
I will explain to you how to make a BIOS update through the BIOS Recovery Mode:
Instructions for Recovery BIOS Updates
In the unlikely event that a BIOS update is interrupted, it is possible the BIOS may be left in an unusable state. The recovery process requires the chassis to be opened to move the onboard BIOS Configuration Jumper.
1. Copy the recovery file (*.bio) to a formatted usb disk.
2. Place the usb disk in the target system.
3. Shut down the system and unplug AC power.
4. Open the chassis and remove the BIOS Configuration Jumper. See the Technical Product Specification for details including the location of this jumper.
5. Power the system on.
6. Wait 2-5 minutes for the update to complete. When the usb drive LED is lit, the system is copying the recovery code into the FLASH device.
7. System will either turn off when the recovery process is completed or it will prompt you to turn off the system.
8. Remove usb disk
9. Replace the BIOS Configuration Jumper.
10. Restart system.
Note: Dont connect any other usb devices, media drive to the system other than just the recvoery media. If you can't do it via the USB, use a blank CD. Then connect only the CD Drive.
Note: these can be found on:
There are other methods as well, Iflash Method, ISO Method where jumper is not required to be removed. etc.
Brief on IFlash:
- Media drive needs to be bootable like bootable USB or CD
- Files needed Iflash.exe, .BIO file
- Command: iflash /pf xxx.bio
Brief on ISO:
- Burn the ISO file on a blank CD using software like PowerIso.
- Boot the system on to the CD.
- Run the batch file
Hope this helps a bit.
