Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:
Turn on the computer, and insert the USB flash drive into a USB port.
Press and hold the power button turn off the computer.
Disconnect all connected devices and cables such as Personal Media Drives, printers, and faxes. Remove media from internal drives, and remove any recently added internal hardware. Do not disconnect the monitor, keyboard, mouse, USB recovery flash drive, or power cord.
Immediately press the Escape key repeatedly, about once every second, until the Startup Menu opens.
Press F9 to open the Boot Device Options menu.
Use the up or down arrow key to select the USB flash drive, and then press Enter.
A window might display, prompting you to choose whether to run Recovery Manager from the hard disk or from the USB drive inserted. If this window displays, select Run program from media, and then click Next.
Follow the on-screen instructions to back up your data and recover your computer.
Once the recovery and setup are complete, turn off the computer, reconnect all devices and cables, and then turn on the computer.
Before using the computer, update and protect your computer. Reinstall any virus and security software that was installed before the system recovery.
Reinstall any software programs that were added after purchasing the computer, as well as any files that were backed up.
Hope this helps! Keep me posted for further assistance.
