Chainloading failure: Toshiba Tecra C40-C UEFI & Samsung SSD MZNLF128HCHP-000

[mabarton]

@Tom-Elliott Our computers go out to students living anywhere in Kansas, so I don’t get to use all of the benefits of Fog. Since the computers are not in my area, I always shut off PXE boot. Our brick-and-mortar uses iPads, primarily.

However, our school belongs to a network of schools called “Teen” and I am hoping to introduce Fog to those schools and a few others in our area. This is Kansas after all, and they don’t like giving schools money.

@mabarton I think, however, this would be the perfect time to learn how to configure rEFInd to enable booting to actually happen without a problem.

I am googling that now.

@mabarton don’t lack on sharing what you find. That way, maybe, I could provide a usable Config for all. After all open source is all about contributing. It sounds selfish I suppose but I would, and possibly many others, be most appreciative of yours, or anybody else’s, findings on this.

[mabarton]

@Tom-Elliott I fear that I would not be much help, but I rarely give up!

The deployment worked!!! I think I am going to have a party to celebrate the end of an entire week of battling this problem. I may be able to leave the school at a decent hour next week!! If it were not for this forum and all of your help, I don’t know what I would have done.

Thank you, thank you, thank you, Tom, Wayne, and George. Your help and expertise have been immensely appreciated!

@mabarton Sorry I’ve been out enjoying the holiday. So image deployment worked, you are able to clone your image to 2 or more target systems right?

The next bit you need to work on is the pxe exit mode stuff (if you want to). Just to recap you’ve selected all of the exit modes for UEFI Exit and none worked. Building on what Tom posted rEFInd should work. While I don’t have personal experience with this issue (yet), if rEFInd does not work out of the box (should be near the end of the list of options). There is a configuration file on the fog server that may need to be tweaked (refind.conf). Its located in /var/www/html/fog/service/ipxe on the fog server. We may need to add additional resources to look for (using the scanfor tag).

@george1421 it has deployed beautifully-- with the exception of the boot looping:)

I am working in the rEFInd, so we shall see if it works.

Thank you for the support!

[george1421]

@mabarton If the default out of the box refind.conf does not work look for a line like this one ( of course the next time you work, and not on your free time).

scanfor internal

This tell refind where to look for bootable devices. You may want to append/change that line to search in a few more places, like this one.

scanfor internal,hdbios

IF that doesn’t work then extend the search a bit more (reminder you need to reboot the target after each change.

scanfor internal,external,hdbios,biosexternal

One of those should pick up that M.2 disk. (said with some hope) We are walking on some uncharted ground here so there will be many trial and error tests until we get it right (or just give up )

@george1421, @Wayne-Workman Sorry, I’m just being a bit lazy after having been offline (visiting a friend in the mountains) for almost a week I am trying to catch up… Is this solved or are we still seeing an issue with this laptops?

[george1421]

@Sebastian-Roth Unless the OP has an update, the answer is not yet. Capture and deploy work to these machines. What is failing still is exiting out of the iPXE menu to boot to the SSD. This is failing. The USA folks typically take this week as a summer break so the OP may be on holiday and will report back next week. The unlucky ones like me still work this week. ;-(

[mabarton]

@george1421 I still have the chainloading failure. You’re right, I have been on vacation. When I am back, I will run the commands you gave me to see if it picks up the M.2. I appreciate the help.

[mabarton]

@george1421 I’m working on this.
rEFInd would not install correctly. I am troubleshooting it now.

[Wayne Workman]

@mabarton I briefly went over this thread because it’s been a while. Have you individually tried every EFI exit type?
