Occasional continuous beep black screen before boot menu fixed by F11

General Help
1

Hi,
I have Zorin 17.2 Core with dual boot Win 7. Occasionally when I turn on the computer, before it shows the boot selection, it makes a loud continuous beep and it freezes on a black screen. Tapping F11 [boot menu key for HP computers] brings up the selection menu, and it starts Zorin with no problem. I replaced the RAM, but that didn't have any affect.
It could be the motherboard, being an old computer, but has anyone had this occur with dual boot systems?

You could search for beep sound if you have the brand of your computer. The indication of the beep will tell you what's wrong/which hardware that's malfunction.

Go to this page and check against motherboard BIOS you have:

Or check with any manufacturer forum that relates to your device.

Thanks I will check this out.

Thanks I found the HP list.

No updates from HP for my computer. Also 'long continuous beep' with red light isn't listed, so I consider this resolved. This is a tolerable problem, as long as
it doesn't get worse.

Do You have Secure Bot and Fast Boot in BIOS turned off?
Do You have Fast Start-Up in Windows turned off?

Maybe GRUB is damaged. You could try with Zorin on an USB-Stick repair it. To do that, start zorin on an USB-Stick and choose the ''Try Zorin'' Mode instead of ''Install Zorin''. Then search for ''Boot Repair'' and run it.

Another Point would be: Is Your BIOS in UEFI Mode or Legacy? And what Tool did You use for creating the bootable USB-Stick with Zorin on it.

@Ponce-De-Leon It's Windows 7 so I doubt any of that applies.

I did boot repair before, to resolve a different issue, it's legacy, and I used Rufus. If it gets worse I'll start trying some other options.

Did some more searching and found this:

"One constant beep can mean keyboard (loose cord or bad), loose card, power, a short or other issue depending on System/BIOS maker."

My instinct was thinking towards a power/short issue.

And when You took Rufus, did You choose on ''Partition Sheme'' for Your Legacy BIOS MBR or GPT? Because MBR could work better with that.

I think it was MBR. I also tried USBImage at one point. I think the first couple installs didn't work.
