Cannot boot peppermint 4 live usb

Hi guys I’m trying to boot into a live usb with Peppermint 4 installed on an old Dell Latitude D600 laptop (Currently running Peppermint 3) but I only get as far as the unebootin menu screen, when I select run live session the following error message appears

This kernel requires the following features not present on the CPU:
Unable to boot - please use a kernel appropriate for your CPU

I know the usb is good as I used it to install peppermint 4 on another PC, also this laptop only has 1gb of RAM so I don’t understand why pae is needed

Any help or advice would be much appreciated

Many Thanks


The error message means that your CPU does not support PAE extensions or the motherboard may not “expose” the CPU’s PAE support,
effectively making them non-PAE.
You would have to use a non-pae kernel. If Peppermint4 does not provide this kernel then you might need to get it from elswhere or try a different distro.
Although pae kernel should function as normal on non-pae cpus, the ubuntu kernel might be an exception to this.

Hi SeZo

Thanks for your reply

So presumably they must have changed that aspect of the kernel after Peppermint 3 because that installed ok

Not all changes are for the better it would seem, but to be honest peppermint 3 is fine it’s no big deal

Anyway thanks for your help


I think Ubuntu dropped the non-pae kernel after 10.04. So Peppermint 3 was OK.
You could go back to Peppermint 3 or pick a different distro with non-pae.
I am using SolydX (XFCE) with non pae kernel. Also LMDE (32 bit) uses non-pae kernel.
Basically you are looking at kernels with 486 instead of 686. Though I have seen some reports that the Debian 686 kernels
seems to just ignore it and run OK.
You could try Debian (LXDE) which can be molded into looking like Peppermint and it is just as lite (or even lighter).

Ubuntu dropped the non-pea kernel AFTER 12.04 … see here:

other than rebuilding the ISO with a compiled non-pae kernel … you’re kinda out of luck I’m afraid :frowning:

Ubuntu dropped the non-pea kernel AFTER 12.04

Well spotted. I meant 12.04 :-[

God knows why … i386 aint quite dead yet … there’s still a few PC’s knocking around.

I mean, I can see no reason for it ::slight_smile:

@ Emegra, if you REALLY, REALLY, REALLY want PM4, I suppose when I have time I could attempt to build an ISO with a non-pea kernel … but if I were you, I’d just stick with PM3 on that hardware.
(if only for the sake of my sanity)

I am so tempted to say I REALLY REALLY REALLY want PM4 on this laptop even if it is at the expense of your sanity, I don’t care I lost mine years ago. ;D

But I’ll give you a break, Peppermint 3 is fine and as it’s based on an LTS release it’s good for a few years yet

if it aint broken no need to fix it

Thank You Mark & SeZo for your advice


You are welcome (not hat I have done much). :slight_smile:
Mark will probably disagree on this, but Peppermint has not got the monopoly on being a “good distro”, there are others too which are just as usable and light.
If you consider that Peppermint will come to the crossroads, when Ubuntu becomes too much an uphill struggle. Soon they will have to decide (along with other derivatives) if it is still worth the effort to make it usable or it is better just re base onto Debian (like LMDE) or some other.

I agree peppermint probably doesn’t have a monopoly on being a good distro but it is a good distro, that said I do like the look of Bodhi Linux and the Enlightenment thing, but then it’s based on Ubuntu as well.

Besides if I moved away from Peppermint Mark would likely never speak to me again (only kidding Mark ) :slight_smile:

I switched to Linux from Windows less than 2 years ago and I,ve always used Ubuntu based distros, in the possibly mistaken belief that they would have the backing of the biggest developer base and a large company (Cannonical) supporting them.

But at the moment peppermint 3 is doing everything I need so I’m happy to leave it as it is for now

Many thanks


Peppermint has no monopoly … but that doesn’t mean it’s not the best :wink:

Only kiddin … it’s not the best in ALL circumstances, and there are a lot of good distro’s out there, so pick whatever suits your needs/hardware :slight_smile:

I too an wondering about this crossroads … I can really only see Debian as a viable alternative … but that’s fine by me, actually it may be a better base than Ubuntu.

The only thing I don’t particularly like about Debian is their strict software/driver policies, but as we have our own repo’s that would be easy to work around … I’m sure we could polish up Debian/LXDE as easily as Lubuntu if the need arises :slight_smile:

Would i be right in saying that in view of the problem i had installing Peppermint 4 on my old laptop (it being a kernel issue), the same problem would arise installing any Ubuntu based distro ?


Unless the distro has gone to the trouble of building a non-pae kernel and including it in their 32bit ISO … YES … any Ubuntu >= 12.10 based distro that hasn’t gone to this trouble will have the same issue.

As you say though … there’s still plenty of life left in 12.04 based distros … probably more life than is in the old laptop :wink:

The biggest change in PM4 … the switch to xfwm4 can be done in PM3 too … that was done based on my having done it in PM3 … so it shouldn’t be too hard to get PM3 to look/behave like PM4 if you want ?

I’m happy to stick with Peppermint 3 on this laptop.

The previous owner had this old thing consigned to the scrapheap more than a year ago running Windows XP because it was far too slow , initially Peppermint 2 and now Peppermint 3 has given it a new lease of life and it does everything I ask of it.

I’ve never cared for the latest and greatest, I was brought up in a culture of make do and mend, I get much more satisfaction from making things work rather than just throwing them away and buying new, and I’ve learned that all that glitters isn’t gold

So I’m happy with this old laptop and I would bet that it will be still be running long after many laptops running Windows 8 are past it


Okey Dokey … PM3 is still a great distro and theoretically 99% of it will be supported longer than PM4, so nothing wrong with sticking with it :slight_smile:

Just out of curiosity I noticed according to this webpage Bodhi Linux does PAE & non PAE versions of their latest distro, unfortunately i can’t check it out for definate because their site’s down at the moment, but if it’s so why can’t Peppermint do it. ?

After all both these distros are lightweight designed for limited hardware which in many cases would include old hardware and they’re both Ubuntu based


Just that you know, Bodhi is based on LTS versions of Ubuntu, so non-pae kernel is still available.

Just that you know, Bodhi is based on LTS versions of Ubuntu, so non-pae kernel is still available.

But according to Marks earlier post all LTS (12.04) and prior kernel versions were non PAE anyway so why bother to give the option

I’m not meaning to be argumentative here, I just don’t understand

Peppermint 3 as i remember didn’t give the option of PAE or non PAE (based on the 12.04 kernel) so why should Bodhi give the option if it’s built on the same kernel?
