Default Boot from CD and Win8.1

Does windows 8.1 do something I thought was impossible and somehow
prevent booting from a CD. I spent ages trying to boot fro a disk and I
can't think what else has happened. The only CD I can boot from is the
8.1 install disk. Any others don't work, although they work perfectly
well on another (W7) system.

Is there a fix for this because I need to boot from a CD to fix the system?

Tim W

I have 8.1 on a netbook with an external usb CD drive. There is a disk
error which chkdsk is unable to fix (gets to 12% and just stays there
all night). The disk error I think is causing the Hard disk usage undr
Windows to rise to 100% and stay there making the system so sluggish it
is unusable.

Is the machine being shutdown, hibernated, or hybrid-shutdown?

try running "shutdown /s /t 0" at a command prompt, then booting the CD

Open a Command Prompt window. Use "cmd" in the Start
thing, right click on it, select "Run as Administrator".

Now, with the trusty black MSDOS window open, type in

powercfg -h off

That turns off hibernation and quick boot.

The reason that is important, is so the next time you shut down,
it's a real shutdown, and not a hibernation operation. It will
also allow you and the BIOS, to select a different boot
device on the next startup. You'll be able to get into
the BIOS, or you can use the popup boot menu (on some machines,
that is F8 or F2 - check the manual or the screen prompt).

*******

Another way to do it is listed here. Disable fast boot (turn off kernel
hibernation).

http://www.eightforums.com/tutorials...ndows-8-a.html

*******

One other benefit of a "true shutdown", is with no hibernation
activity at startup at all, C: will not be busy, and any previously
scheduled CHKDSK scan of C: can commence just before
the OS mounts C:.

*******

You can also boot the installer DVD or the recovery CD, and access the
MSDOS command prompt window available there. You can run CHKDSK with
a fix option in there if you want. The results should not be any different.
If the file system is in some sort of loop, I expect it'll still be
stuck in a CHKDSK loop.

The chkdsk command has some subtle differences, between the
version in Windows 8, versus the version in the recovery console.
If you have a second Internet=connected computer available, you
can look stuff up while you're using the recovery CD and the
command prompt window.

This is the recovery CD menu with the Command Prompt option at
the bottom.

http://www.sevenforums.com/attachmen...ry_options.jpg

More pictures of how to get there, are shown in the accompanying
article. The installer DVD can attempt to repair things, whereas
the main purpose of the recovery CD (~200MB size) is as a means
of getting a working Command Prompt. Or doing a restore from
a Windows Backup.

Yes the motherboard developers and Microsoft joined together to come up
with UEFI as a replacement for the older traditional BIOS starting with
Windows 8.0 if my memory is working correctly.

I'm not going to go into the why they wanted to replace BIOS as that can
get quite political in a hurry.

http://www.howtogeek.com/56958/?PageSpeed=noscript

What it does boil down to is if you are trying to use older Linux as a
emergency recovery method you are pretty much blocked.

The Linux people have not taken this change lying down however. You can
now get UEFI approved Linux distributions.

Here is a link to one such distribution that you might want to download
and burn to see if UEFI is your problem. Give Fatdog64 a try which can
be found at;

http://distro.ibiblio.org/fatdog/web/

Yes there may be ways of turning off the UEFI on your motherboard if you
can gain access to the firmware but I'm no expert on the subject and
suspect it would take a fresh install of Windows to make it workable
again after making the switch. Hopefully others will chime in here an
give you some better advise.

At least trying the Fatdog64 Linux should not cause any further problems
than you already have as long as you just run it from the CD and don't
give it permission to actually install itself onto the hard drive.

Another option would be to pull the hard drive or SSD
from the computer, and connect it to another computer.
One where you have control over booting. That isn't very
practical for mobile devices where the storage is
a flash chip soldered to the motherboard.

Linux will not mount a hibernated Windows NTFS partition.
If kernel hibernation is being used, it's also possible
you won't be able to work on it. Linux has a rule about
hibernated partitions. I only discovered this recently, when
attempting to work on a Win8 disk which came from a computer
in (full) hibernated state. I haven[t tested a Quick Boot
(kernel) hibernated disk, to see if that is the same.
The dialog box in Linux, suggested bringing that system back up
and doing a full shutdown, and then I'd be able to mount it
for work in Linux.

*******

The Secure Boot policies are described here.

http://en.wikipedia.org/wiki/Hardware_restriction

"In January 2012, Microsoft confirmed it would require
hardware manufacturers to enable secure boot on Windows 8
devices, and that x86/64 devices must provide the option
to turn it off while ARM-based devices must not provide
the option to turn it off."

So that means a Surface, you can't turn off Secure Boot.
Whereas a Surface Pro (Intel) you can turn it off.

In cases where Secure Boot is present, it is also possible
for the OEM to place both Windows and Linux keys for
Secure Boot. I expect the case where Secure Boot cannot
be turned off, it wouldn't make sense to have more than
one set of keys in there. Might as well make the device
unmaintainable, and fit to be thrown away with the
slightest problem.

Thanks Andy, Paul, GBM.

It looks like I am stuffed here. Not to worry, it was only an old
netbook that I was mucking about with for fun.

I have had xp win 7 win8.1, several different linuxs and OSX running on
this netbook and am very unimpressed that Win8.1 should bork it beyond
repair. I don't see much point in running chkdsk again and again. I was
going to try to run an alternative check fix and format utility.

There's a couple possibilities.

1) You issues a CHKDSK command that just checks the file system.
That should complete relatively quickly (maybe 3 minutes). If
it goes off for 12 hours in that case, then something must really
be in bad shape.

2) If you tell CHKDSK to read every sector (in an attempt to segregate
bad clusters and have them added to the $BADCLUS list), then you can
easily get stuck for 12 hours on a "bad patch" of the disk drive.
In such a case, I'd switch back to the test in (1), to try to
fix the actual file system well enough, so it can be backed up.
Then restored to a good disk drive.

The SMART parameters for the disk, can tell you something about
hard drive health. But I've had one disk here, where the SMART was
still good, and there was definitely a bad patch in the disk. I took
the disk out of service, because a transfer rate benchmark showed
the bad patch (always slow when reading in that section).

It's possible (1) will run well enough, so you know the data
is in relatively good shape. If a full disk scan sector by sector
takes 12 hours, then there might be a bad patch doing that. As far
as Microsoft is concerned, the purpose of the full disk scan is
to mark bad clusters via the $BADCLUS list (so they won't be
reused again). Whereas to me, if your disk is that bad, it should
just be replaced. A scan with a tool like HDTune, which just reports
CRC errors, is good enough for the purpose of throwing a disk drive
in the trash, if that's the kind of test you want to run. CHKDSK
wouldn't be all that good a choice for disk drive testing. But CHKDSK
is your only choice, if there is something wrong with the MFT
(Master File Table) or the like. File system structural problems,
that's the only tool of any merit.

Also happens on non-uefi configured system. Been there, done that

Only option I found was just use the bios boot select & selected
boot from the cd; then was able to re-install win7. Still don't know
how win8 did it.

Yeah I don't know about uefi this isn't a very new machine and Windows
didn't give me a page for uefi config and disabling Secure Boot. I have
refromatted the hard disk now but I still can't get it to boot from a
usb cd or a usb stick to put any OS on it. I think I might buy one of
those Win8 tablets that are so cheap now to replace it.

Do you have the options set in your BIOS to boot CD,USB then HD? I have a 4yr old laptop with no UEFI also but I get
the cd prompt all the time. Odd though I put in a win8 cd yesterday and it booted, no prompting. But put in a Linux
Gparted Live boot CD and it gave me the "press any key to boot from CD..." prompt. I always thought that was the
default question. Oh well.

AFAIK, that's on the CD itself, i.e., part of its boot code.

That's because I *think* I remember when I was using Macrium or Gparted
or one of those to make a boot disk, it gave me the option to set up
either way. It wasn't very recent, so I'm shaky about that memory.

I was finally able to transfer the whole win8 DV onto a bootable usb
stick and hooray! we are back in business! Windows installing as I type.

Don't know if I will have fixed the original problem, lol.

Secure Boot is enabled on your PC. Disable it in UEFI (your 'new' BIOS):

Also happens on non-uefi configured system. Been there, done that
when trying to re-install win7 from win8 the 1st time.

Only option I found was just use the bios boot select & selected
boot from the cd; then was able to re-install win7. Still don't know
how win8 did it.


Yeah I don't know about uefi this isn't a very new machine and Windows
didn't give me a page for uefi config and disabling Secure Boot. I have
refromatted the hard disk now but I still can't get it to boot from a
usb cd or a usb stick to put any OS on it. I think I might buy one of
those Win8 tablets that are so cheap now to replace it.

Do you have the options set in your BIOS to boot CD,USB then HD? I have a 4yr old laptop with no UEFI also but I get
the cd prompt all the time. Odd though I put in a win8 cd yesterday and it booted, no prompting. But put in a Linux
Gparted Live boot CD and it gave me the "press any key to boot from CD..." prompt. I always thought that was the
default question. Oh well.


AFAIK, that's on the CD itself, i.e., part of its boot code.

That's because I *think* I remember when I was using Macrium or Gparted
or one of those to make a boot disk, it gave me the option to set up
either way. It wasn't very recent, so I'm shaky about that memory.

I was finally able to transfer the whole win8 DV onto a bootable usb
stick and hooray! we are back in business! Windows installing as I type.

Don't know if I will have fixed the original problem, lol.

I know you feel better though. Been there, done that!

When your computer boots up, press F2 several times. It'll give you access
to the BIOS where you can disable UEFI.
