(Solved) Boot from CD loads old configuration

[athouston]

I got this problem trying to build a new TCL from the latest download (4.7.7) to replace my 4.5.6.

I boot on the CD of 4.7.7 and it comes up with the correct boot screen but then loads the old system from the hard drive. My assumption was that I could boot on the new platform from CD, install cfdisk to clean off the partitions on the hard drive, and use tc-install and do a clean install.

I cannot clean of the hard drive partitions because umount says the the device is busy.

My hard drive is actually a 16GB CF card on an IDE adapter that plugs direct onto the motherboard so I cannot hot plug the card in after bootup.

Any suggestions how to overcome this.

Boot code "base".

Why not just copy the 4.7.7 core.gz over the 4.5.6 version on the hard drive and run tce-update?

Thanks TinyPoodle - Boot Code base was what I was looking for. All good.

gerald_clark - I asked in another thread a similar question and got a different answer, although both are valid. Given that I was having a raft of problems doing an ARM install I decided to go for the clean base option because I didn't know everything about what I was doing. I broke out a new 16GB CF Card and started from scratch.

I will however now play with your suggestion for future use as it will be much harder to rebuild a system from scratch once I have my project up and running.

Thanks again.

Oh, you did not mention ARM, and did not post this in one of the ARM subforums.
You have a 4.5.6 ARM version of TC?
I thought the ARM versions were more recent then that.

Sorry, I posted insufficient info. I was trying to do an ARM installation but was being frustrated because my x86 TCL version (4.5.6) was not up to snuff enough to run the necessary routines to build the ARM image on another SD Card. I needed BusyBox and some other bits; hence the need to upgrade.

Thanks for the follow up.
