    Posted: 13 Nov 2015 at 4:11pm
Hello all.

I have a very strange problem since i upgraded me Q1900M system from windows 8.1 to windows 10. Most of the times, when i reboot the system, i get a blinking cursor after system post and system stays there forever. If i turn off the power and then start the system it boots up normally.

Any idea on what might be causing this problem or how to gather more information about it? The system is used as a media server (ie no keyboard - mouse attached to it). 

Using latest BIOS.

Thank you in advance for your answers.

Regards

I have the same problem, but with the Q1800M. Freshly installed windows 10 often never gets to boot because post stops with a blinking cursor.

Factory settings on the UEFI. Anything we should try changing there?

This is directed at the both of you above. episilon and fdmsaraiva.

Will it boot into Safe Mode?

Also, please read and follow my sig. It'd be helpful to have a better, hehe any!, understanding of what your systems are comprised of.

What I know now of your systems will serve absolutely no use in helping either of you.

Hi wardog and thank you for your reply.
The problem occurs after bios posting so boot sequence have not started yet in order to choose safe mode. The funny thing is that it doesn't always fail (i would say 3/5 times). So since it's not 100% reproducible, it's quite hard to track it.

Ditto. I would only add that to me it hasn't yet happened with a cold boot, only with restarts.

Do either of you have a POST code speaker connected to the board, in case you are getting a POST beep code that may give a clue to the problem?

The Windows 10 fast startup feature only works from a cold start, not on a restart. You could try disabling fast startup for a few cold boot and restart cycles. If that then clears the restart problem, try to enable fast startup again.

From the main Power Options screen, click on the Choose what the power buttons do option, and you'll find the fast startup entry in the lower part of that screen.

It seems as if neither of you have the Fast Boot option enabled in the UEFI? (Unrelated to Windows fast startup.)

Can confirm this issue as well - I'm running a Q1900 DC-ITX (with latest 1.20 BIOS) here.
When rebooting it from within Windows 10 (latest 1511) it hangs in most
cases with a blinking cursor... but a cold start always works fine.

It doesn't seem to be related to 'fast startup' as well - because I doesn't
have it enabled.

However - I'm running the same board in some linux servers too - and they
are all _not_ affected by this because of a recent patch to the linux kernel, see:

http://www.gossamer-threads.com/lists/linux/kernel/2140005?do=post_view_threaded

and its commit

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/x86/kernel/reboot.c?id=80313b3078fcd2ca51970880d90757f05879a193

which effectively fixed this for me on at least linux.

Problems for Windows:

1) How can one mimic this reboot=pci on Windows (it at all possible)
2) Isn't this a BIOS issue (with latest 1.20) which should be fixed by some clever ASROCK tech?

HTH,

No speaker installed but i'll try to pin one today and try to reproduce and see if it beeps on reboot.

Fast startup is not enabled in UEFI (by default) and fast startup entry does not show up in windows power options (i guess it's linked with the disabled option in UEFI).

hellos,

... after filing this forum thread hint into their (asrock) official support queue
some very kind tech provided me with some (not sure how to name it) BIOS
prerelease or beta version (1.27) which fixed this issue for me on Windows 10 Pro
as well now.

@ASROCK - good job - thankyou!
