Can't Boot from Win 10 Rescue Disk

dalchina said:

Setting boot priority for an optical disk is a different setting to the flash drive.

However yours is an HP machine, and this says there's nothing to do in the BIOS for these:
HP PCs - Configuring the Boot Order in the System BIOS | HP® Customer Support
That said, it's worth checking.

Also I've found this:
These options have to be changed if you want to boot from an external device like an USB stick or a bootable CD-media. Please change the option "Secure Boot" to "disabled" and the "UEFI Boot" to "CSM Boot" in order to allow the system to boot from external devices.

(I've not had to do the second - it just works).

That would imply if you can boot from a flash drive, you should be able to from a DVD.

The CD may not be UEFI enabled, while the USB is , if made like I said above , so you maybe correct about the CSM (legacy) setting , my Bios has it enabled by Default but perhaps HP's don't ?

A Windows 10 MCT created Bootdisk is UEFI I believe so it should work

Kbird, This system does not have Secure Boot because it was a Win 7 system upgraded to Win 10. I have no idea about FastBoot.
However, today I successfully booted the Rescue CD that Backup & Restore (Windows 7) created. And the rescue stuff was there and working. I'm going to test doing that again.

dalchina, I am not trying to change the boot order. I'm selecting a boot device to be used one time. This PC does not have Secure Boot. I have not changed UEFI Boot to CSM Boot. However, as noted above, I have booted from the Rescue CD today and will test doing so again.

Hopefully I'm actually making progress.

Hi, you're right- it's easy to forget about non-UEFI BIOS - and your PC came with Win 7 so does not support UEFI or secure boot.

Fast start-up is part of Win 10, however. (I think that's what was meant by Fast Boot).

A useful boot disk to have is here:
Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums

It's good you're thinking about system imaging- we recommend disk imaging strongly, but prefer 3rd party solutions being more reliable, flexible, and feature rich.

Macrium Reflect (free) is often preferred, particularly for system images. It's GUI is, however, more technical than some of its competitors. It's well supported, with a good forum, help and videos, and kept updated,

I use Kyhi's 160707 bootdisk too , very handy to have , I am not sure if UEFI or not though , not that it matters except for testing.

Fast Start Up is Win10 , Fast Boot is part of the Bios , but I think they probably interact since Win10 can now Alter the Firmware (Bios) as needed. I have both disabled as it stops WOL working ..at least on my intel Nic and I am not worried about saving 20secs at boot or Hybrid Sleep.

I would suspect the Backup and Restore Disk is non-uefi since it is a Win7 program ,even my 5yr old X58 Chipset MB is capable of booting EFI CD/DVD's but I have no idea about that HP System.

I too use Macrium for my backup images , lots of help here on using it if you need it as most people here use it....

A couple comments: My system is UEFI. I don't think it has Secure Boot. I've never seen anything about Fast Start Up or Fast Boot. dalchina referred to system imaging and disk imaging. I think of a System Image (like backup & restore makes) and Disk Imaging as very different things. Loosely , a System Image is a set of files that contain the source disk's files and other data structures. It does not look like a disk. Whereas a Disk Image (aka clone?) is an exact, block by block copy of the source disk. I only have System Images.

I can reliably boot the USB Drive.

I can boot the Rescue CD spasmodically using UEFI and selecting the CD/DVD drive. I think it always fails if I try the legacy boot option for the CD/DVD.

I'm still going to find a DVD disk and burn Kyhi's iso to it. Hopefully I will be able to reliably boot it.

Macrium can Image a Disk and it can do a Forensic Image (sector by sector) but typically it only backs up used Sectors (Intelligent Copy) with medium Compression , so "Images" are usually about 75-80% of the Used Space as seen in File Explorer.

You may not have FastStartup in Settings>Power>Power Buttons , my older X58 system does not. My X99 does though.

FastBoot is usually an option in the Bios , in the boot section along with the ability to disable the Bios Boot Logo (so you can see post messages) etc , set the Boot order , that sort of thing. and CSM if you have it ? something like this here 1st 3 images.......

I now have Macrium Reflect Free and have created a rescue disk (on CD) and a first disk Image backup (on my external backup disk).
The rescue disk boots (I've only tried the UEFI option) and I can mount and explore the disk image. I think this gives me the basic tools I need. My ultimate goal is to change the partition sizes on my C: disk but I wanted a way to recover the whole disk if something goes horribly wrong. Changing the partition sizes is a whole other adventure and, if necessary, will pop up in another thread. It's my understanding that Win10 can change the partition sizes without having to use a 3rd party application but I also have the Partition Wizard application. Wish me luck, I'll probably need it!

And thanks for all your help with my rescue disk booting issues.

Make the MTPW Bootdisk too or the Kyhi Boot disk which includes it and Macrium Reflect and other Handy Apps too.
