I’m trying to clean install Proxmox, and it keeps failing. I’ve played with the USB drive and tried various versions, including the latest version, which still works. However, I’m afraid I may have messed something up, as I messed with the .conf files and some other stuff trying to get the SRIOV to work. Although I can still boot into the installed version, I’m concerned that I may have messed something up. Thanks for any help.
Not sure what your issue is.
seems to contradict
To help with this, the good folks here would need to know which files were altered and how.
Generally, I am confused by statements like:
How can the latest version still work, if the install keeps failing? What did you do to the USB drive? And what role does the USB drive play in your proxmox setup (install medium/root drive/storage drive)?
Your post - at least from my perspective - doesn’t allow any assessment of your current situation.

I already installed 8.2 and wish to install it again as im not sure it is the way it was prior to messing around with it. The USB drive was formatted and I installed the bootabke ISO from proxmox to it several different ways prior to giving up and coming here to ask for assistance.
8.2 still boots abd functions but I dont want to risk it failing because Screwed around with it. Ill get the file name when im back in it. Appreciate the response although it points out the pleb that I am when it comes to linux😉
The USB is installation media only. I am installing on a NVME drive in a Minisforum MS01.
A nice tool allowing to live boot or install OS from a selection of ISO files is Ventoy. If you’re unsure about your install medium I’d give this a try.
Install Ventoy once, and simply file copy a couple of ISOs onto the drive, including maybe several versions of Proxmox if you want to try them out.
i have tried it i like it. still getting stuck
Guessing you don’t have a support contract. I don’t either. The forums there are unfortunately rather slow and unhelpful in most cases. I found the proxcord discord server to be pretty helpful for proxmox specific issues. It sucks that it can’t be in a forum kind of thing for future use, but you can always make a post about it after you figure out the issue.

Maybe you can describe the steps you take until you’re getting stuck. Key questions:
- Which method do you choose to install Proxmox? I assume the graphical installer.
- Does the Proxmox installer start up?
- (if yes) what do you use as install medium? e.g. are you trying to overwrite your existing install?
- (if yes) did you format existing drives/partitions for install?
- at what step in the install instructions do you “get stuck”? What does that mean?

Issue: Installing NVIDIA 3060 GPU via PCI Extension Ribbon
-
Hardware Setup:
- Attempting to install an NVIDIA 3060 GPU.
- Using a PCIe extension ribbon, supposedly PCIe 4.0 x16.
-
Problems Encountered:
- The GPU is not visible in BIOS.
- The GPU is not detected by any VMs.
-
Initial Troubleshooting Steps:
- Expected the Nouveau drivers to detect the card but they did not.
- Tried two different new PCIe extension cables with no success.
- The GPU is new, so hardware failure is unlikely.
- Changed vatious bios settings multiple times without success.
-
Driver Issues:
- Attempted to install NVIDIA drivers without success.
- Suspected a potential conflict with a recent update and NVIDIA driver compatibility.
- Nouveau Drivers are now loading but I originally blacklisted them.
-
Questions:
- Shouldn’t the GPU show up in BIOS regardless of driver issues?
- Is it a Bios issue. I still have the boos it shipped with in it.
Thanks
You’re encountering several issues while installing an NVIDIA 3060 GPU via a PCIe extension ribbon. Let’s address your questions and the overall situation step-by-step:
Questions and Issues:
- Visibility in BIOS:
- Shouldn’t the GPU show up in BIOS regardless of driver issues?
A GPU should typically be visible in the BIOS/UEFI even without any drivers installed. The
BIOS detects hardware directly connected to the motherboard, including GPUs. If the GPU is not
showing up in BIOS, it suggests there may be a hardware connection issue or compatibility
problem with the extension ribbon or motherboard.
-
BIOS Settings:
You mentioned trying various BIOS settings without success. Make sure to:
Check if the PCIe slot where the extension ribbon is connected is enabled and set to the correct mode (e.g., PCIe 3.0 or 4.0, depending on your motherboard and GPU requirements).
Ensure any relevant settings, such as Above 4G Decoding, PCIe Gen settings, and any specific GPU settings, are correctly configured.
Sometimes, updating the BIOS to the latest version can resolve compatibility issues, but this should be done cautiously and following manufacturer instructions. -
Extension Ribbon and GPU Compatibility:
Ensure that your PCIe extension ribbon is compatible with PCIe 4.0 x16 speeds. Extension cables can sometimes cause signal degradation or compatibility issues, especially if they are not good quality or designed for high-speed data transfer.
- Driver Issues:
Since the GPU is not even detected in BIOS, driver issues should not affect its visibility at this stage. First, focus on ensuring the hardware is recognized at the BIOS level.
- Hardware considerations:
Double-check all physical connections: the GPU seating, power connectors, and the PCIe extension ribbon connections.
Verify that the power supply unit (PSU) can adequately power the GPU, especially if it requires supplementary power connectors like 6-pin or 8-pin PCIe connectors.
Steps Forward:
Physical Inspection:
Power down your system entirely and physically reseat the GPU in its slot. Ensure it is firmly seated.
BIOS/UEFI Configuration:
Go through your motherboard manual to ensure all necessary BIOS settings for PCIe slots and GPU configuration are correctly set.
Check all power connections to the GPU and the PSU.
Testing without Extension Ribbon:
If possible, try installing the GPU directly into the motherboard’s PCIe slot without the extension ribbon to see if it is detected. This can help isolate if the issue lies with the ribbon.
Update BIOS (if necessary): Consider updating your motherboard’s BIOS to the latest version, especially if your current version is significantly outdated.
Compatibility Check:
Verify the GPU’s compatibility with your motherboard and the PCIe extension ribbon. Some combinations may not work well together due to compatibility issues.
Consult Manufacturer Support: Contact the motherboard and GPU manufacturers’ support for specific troubleshooting steps and known compatibility issues.

Thanks for the detailed response. I have a 90 degree pcie card extension coming tonight so I can tey connecting it direct through that.

The cable could be an issue
because the PCIE slot on MOBO is only 8 lanes x16. The fact the ribbon cables have 4 or 5 separate bundles of cable for noise reduction may cause issues given this alone correct?
-
We have enough power its a new 850 watt corsair modular unit. Mind you the MOBO doesnt connect to this at all its only the card right now. The PSU doesnt light up and the fan stays off but i have read that these do that i believe. Power saving. They need a light imo. -
Im pretty sure the setting in BIOS are good for now and im leary of messing with it. Its possible to brick these Ive heard. -
I have reset the card multie times and played with the ribbon and determined a poor connection is unlikey at this point. -
If i get it to register in bios should i use the nvidia driver and dkms package etc… I already tried and keep getting errors so that wull be next if so.
Tha k you
Well, do not only try the “correct mode (e.g., PCIe 3.0 or 4.0 […])” but also the lower settings.
I suspect both your card and motherboard to support PCIe 4.0 but due to the added cable reducing the signal quality only a lower standard may work in your setup. Forcing a lower speed may not what you ultimately want, but it could identify an issue.
Also look for bifurcation settings for your slot. Bifurcation is a feature that allows separating the electrical lanes of a single PCIe slot in order to connect multiple devices to these lanes and operate them in parallel.
In case you inadvertently enabled bifurcation for the PCIe slot in question your card would use less lanes. Most cards still work with less electrical lanes connected but it is another potential source of issues.
It might be that you are on special hardware, server board, or ITX and smaller but using yet another adapter is not really constructive. I know it sucks having to disassemble a build, but you should cover the basics first and that’s running addon-cards without any intermediary.
