How to solve, "Reboot and Select proper Boot device"

Anonymous

This keeps showing up when I turn on my computer and I cannot resume.

"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"

This shows up again after I press a key.

This happened when I connected the master plug part of the ATA Cable to my hard disk because I saw that it was connected to the slave part of the ATA Cable. I din't meddle with the jump block because I didn't know what to do to this.

When I open my computer I saw this problem.

I connected back the slave part of the ATA of my hard disk to see if I undo the problem but when I open my computer, still this problem shows up.

What can I do. My HDD is Hitachi, 80GB, 7200RPM and this is only one HDD in my computer.

I also have a question.

What is a Slave and a Master Drive?

What's their difference?

Hi Sora,

Thank you for posting your question in the Microsoft community.

I understand that whenever you start the computer you see the message “"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"

Usually this error message occurs if in the BIOS, booting is set as to start from CD Rom or floppy drive as first boot device. Where as you are trying to boot from the Hard disk.

Go into BIOS and change the Drive Boot Order so that the Hard Drive comes first as a boot priority. You should be able to boot into Windows normally after you save it to that configuration.

Note: Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

For help with the BIOS settings, refer to the computer manual or contact the manufacturer.

This keeps showing up when I turn on my computer and I cannot

get of it"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"

The screen is just plane black, I tried unplugging everything and then plugging every thing and then plugging them back in, and then I tried a whole bunch of other things I found online but not even one worked.

yeah I have this question too, but these Microsoft computer guys are talking like nerds (Not the candy)

(And I'm not trying to be mean or any thing)

Hi there,

I had the same problem with my desktop, the first time I was able to just go into my BIOS and change to my hard drive, reboot and it worked. Then two days later the same problem but when I tried to change back to my hard drive, it wouldn't work after multiple attempts. I tried too restore default settings multiple times, still nothing. So noticing how dirty my fans were I thought I might do some spring cleaning. I disconnected all of my wireing and blew everything out with caned air. After I put everything back together and was hooking my tower back up to my monitor, I decided to change what port I've normally used for a long time. Luckily I was able to boot my computer back up with no issues.

After all that I got it working, I'm not too sure if it was cleaning all of my wire connections or changing what port I use for my monitor put its been working for a week now and no issues so far.
