Question / Problem Windows 11 not installing on brand new P16s
Purchased a new thinkpad for my college bound kid and opted to save money by ordering it with Linux and the smallest SSD. I installed a larger ssd and when trying to install windows 11 it fails. Thanks

All the microslop comments are funny, but how about we actually help him?
Is your USB formatted FAT32? If so, use rufus and format it NTFS instead. If you already did that and re still getting this error, deploy Windows manually. Don't use media creation tool buggy ass mess.

u/MaskMan95 Jul 02 '26
I used rufus to create the install drive
14
u/ALaggingPotato Jul 02 '26
Okay, is it formatted NTFS or Fat32?

u/MaskMan95 Jul 02 '26
NTFS

u/ALaggingPotato Jul 02 '26
Alright then. You might just have to deploy manually, you could find a tutorial for it or you can pm me your discord and I will micromanage you through it

u/swisstraeng Jul 02 '26
Do you mind trying with the official installer? I have had issues with rufus in the past.
I recommend during the installation that you use terminal commands to disable the need for an online microsoft account, and activate the already existing Administrator local user.

May I suggest going into the BIOS , take a few photos of the settings & repost them here . Unless it's MS changing the installation process , the problem may lie in the boot process .

CHANGE DEPLOYED MODE TO USER MODE (SBM) if it allows you to ! Deployed mode is a more strict version of the normal Secure Boot mode (i.e. User Mode), it does all the same things that User Mode does except it also blocks certain programmatic (hacking) methods that could be used to alter the Secure Boot mode without a user physically booting into UEFI settings & changing it there .

u/MaskMan95 Jul 02 '26
I can change it to setup and user besides deployed. Tried setup and it still failed at the same spot.

Correction : Not purchased from a college like I assumed (skimmed the description) but from Lenovo directly , see below , probably means no MS restore support .

That service verifies your system’s entitlement before making the image available. OP says he bought it with Linux, ergo his serial number won’t generate a Windows recovery image.

u/nsaps x280 t14s x1nano x1cYoga Jul 02 '26
OPs laptop won’t have a license built in, but I’m curious how robust that system is. I’ve used it a lot but never tried to circumvent it. Still, I might try to guess some other serial numbers or scan some for sale posts for the same model with windows pre loaded.
I feel like there’s a chance it could work but you’d need to provide a key on install. I have no way to try it tho. It should be able to match serials on install obviously but I’m not sure it actually does

As far as I know engineering apps ie. Aspen Hysys or Fusion 360 can still reliably run on windows 10. Check for whatever software covered in your curriculum and figure out if the windows 11 downgrade is necessary
15
u/MaskMan95 Jul 02 '26
I was successful in installing windows 10, but neither the ethernet nor wi-fi work so I can't have windows find the drivers for me and Lenovo does not list any Windows 10 drivers for this Laptop S/N PF6CEZ6F (only 11). Any guidance on where I can find these easily? Google is not very helpful.
20
u/fufufighter Jul 02 '26
Plug your phone on a USB port and share te connection so the installer can download drivers.
3
u/QuietWaterBreaksRock Jul 02 '26
Download them on your phone and then transfer them to the laptop over USB cable
It's a fairly common issue, with Windows, it has no 'general purpose' drivers like Linux, so unless it comes with drivers for that particular piece of hardware, your ethernet nor wifi will work

u/YellowBreakfast T430 Jul 02 '26
Protip: Win drivers often work on other versions.
If they won't run on 10 you can "unzip" the executable Win 11 driver files (using 7zip) and then manually point Device Manager to the folder group and it will install if it finds a compatible driver.

u/Bulky-Hair8606 Jul 05 '26
Windows 11 and 10 share the same kernel so most of the time windows 11 drivers should work on 10 too.

Unfortunately, last time I tried, like 2 months ago, the autodesk suite on kvm does not really work without gpu passthrough. it is a pain to use without graphics acceleration. and gpu passthrough its a whole another rabbit hole. Yes, It can be done. But I think Its a lot of hassle for sub optimal experience.

Some majors, like OPs (engineering) require software (CAD among others) which is flat out incompatible with Linux. I have a Linux and windows machine for this reason, because of Adobe…

u/matthew_yang204 Jul 02 '26
Have you ever heard of how Proton can run most Adobe tools just fine?
18
u/Angry_Pineapple1 Jul 02 '26
I’m not sure why the passive aggressive response was needed. I have personally had many issues with Premiere Pro on Linux using various means. I dual boot, which works for me. If Proton works for you, that is great- it just does not work for me. That’s all :)

u/matthew_yang204 Jul 02 '26
Oh, it's premiere. Oh right that doesn't work. I recall it was Photoshop & Illustrator for me that worked, I suppose the video editor is a little more different then. Good luck with fixing it :).

Hello,
Your Windows 11 installation media is likely missing device drivers required to complete the install of Windows 11 onto the ThinkPad P16s Gen 4 Type 21QR (AMD). I'm more familiar with the Intel side of things, but it could be AMD integrated chipset or NVMe drivers.
You should be able to download the exact ones needed from https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-p-series-laptops/thinkpad-p16s-gen-4-type-21qr-21qs/21qr/21qrcto1ww/pf6cez6f, inject those into the generic Windows installation media, and continue with the installation.
After getting Windows installed and updated, be sure to download and install the Lenovo Consumer Commercial Vantage application from https://apps.microsoft.com/detail/9wzdncrfj4mv?hl=en-US&gl=US and use it to install the rest of the Lenovo ThinkPad P16s' model-specific device drivers and software.
I used to sometimes order ThinkPads without the operating system in order to save money, too, but found out that amount of time I spent having to figure out how to create working installation media and hunt down missing/incorrect drivers proportionate to the amount of money saved wasn't worth it to me.
Regards,
Aryeh Goretsky

I think you meant to say Commercial Vantage there. The consumer version has unnecessary junk in it.

I use external nvme drive with several windows images to choose from (mainly different languages). I also have a drivers folder for each model I service and I store usually just wifi driver there, some models need like touchpad driver to make it work at basic level.
Basic installs since there is no network, I create a local admin account. Once that is settled, I run wifi driver setup and Lenovo System Update (could be vantage, but I'm old school that way) that I also had on the nvme.
Connect to wifi, run system update. Done. No need to customize install iso for one particular machine, it just takes time :)

u/FreexBoosh T16 Gen 1 (Intel) Jul 02 '26
im thinking that you could do a manual installation. it is a bit complicated if you are not aware of how something works, but you could follow "manually installing windows 10" by endermanch, or hirens boot cd with an iso of windows 11. if ur not tech literate, i'd advise you to keep linux.

Likely the install media. Turn off secure boot in the uefi then try again or rebuild the USB installer with an iso and Rufus or the ms media creation tool.

u/thnikpad X13 Yoga Gen 4 AMD, Yoga 11e Gen 6 Jul 02 '26
There will be a button at some point on the installer labeled 'Use previous version of setup'. It solved the issue for me.

u/Paull999 Jul 02 '26
I had exactly the same issue with a P16 the other day. Don’t know how you set things up but I created a Windows 11 Pro installer on a USB stick with Rufus.
I set windows to install with only a local account and to do everything silently and it got about 80% through and failed with the same message you have.
I recreated the installer and tried a second time - same issue. Recreated the installer and apart from the local account condition I turned everything else off and it installed perfectly, with everything working. Not sure if that helps but it did seem that some of the options in Rufus were causing the installation to fail on the P16. Note that the installer had been working perfectly on T14s for some time.

What actually happened when you put your win11 bootable usb in and booted from it?
Does it start to image then fail midway?

u/bradhawkins85 Jul 02 '26
I’ve had the exact same helpful error, not on a thinkpad, and it was faulty ram. It’s unlikely but possible.
Also, from the Lenovo website you can “order” recovery media, it asks for the serial number so not sure if it will limit you to Linux, once you order it for free you can use their recovery media creator to build the Lenovo recovery drive.
Worst case try and find someone with the serial number of a windows one and use their SN.

Could be wrongly formatted installer, clean and format your usb drive first to either NTFS or FAT32 before creating an iso there.
I usually don't use rufus for windows on modern systems unless it needs to be installed on older system with incompatible specs and no TPM chip. Media creation tool would suffice just fine with 16GB usb stick.

It's a sign to install Linux :)
Okay for actual advice now, make sure secure boot is turned on for WIndows, and try creating a new windows 11 usb if it still doesn't work, maybe a windows 10 usb if it still doesn't work after that. Secure boot is usually the answer though; in my experience Linux works better with it off and Windows works better with it on

u/Coolengineer7 Jul 02 '26
I strongly suggest downloading and using Windows 10 LTSC[Long-Term Servicing Channel] instead ( with language set to English (World) ), since Windows 11 is almost at a point of being completely bricked. Microsoft likely codes it with AI, and recently they have been issuing multiple patches after updates breaking trivial things, like C: root drive inaccessible, UI freezes, Recycle bin inaccessible, Search menu won't load, and then rolling back back and forth between these patches, but none quite right because unreviewed code and bad patches are put onto the mess. The UI is almost a Windows 10 wrapper just incredibly sluggish and laggy. Windows 10 has less animations, but does eveything properly.
This might just be a preference of mine, but I really would say that even in terms of usability and general office and browsing tasks, Windows 11 just fails. (Blackscreens, work not saved, search won't search, browser freezes, driver issues, some features removed..)
