Hello, that's a really powerful system! 😀
I wished I had something like this (+little more RAM) when I got my first copy of Vista.

Unfortunately, I can't really give you an advice because of this.
Back in the golden days of bluescreens I used to use something like a Pentium 75 w/ 16MiB RAM and a 500MB HDD. 🤣
And an S3 Trio or Cirrus on-board VGA. It may sound silly, but that's what I had most of the time.
It was enough to run Need for Speed II SE and to do school work, at least.

But back to the topic - you can try to launch setup with some of the undocumented parameters.
Maybe this helps (skip auto-detection and/or ACPI/APIC).

Good luck! ^^

Cool! Take care of 4K sectors (+alignment) and LBA48, though. 😉

Bios is resetted cause of empty battery. Now what could it be. The Bios, the GPU or the Harddisk? Next to try is to disable all the hardware n the bios, even the sound and Networkcard. Should i enable or disable the PNP-OS function in the Bios?

Hard to say. It's Windows!

Anyway, I'm assuming you've replaced the CMOS battery, which is important. BIOS should be set for a PnP OS. Disable all the hardware during install and possibly even use an external video card.

Yes to everything you said about disabling stuff. I don't trust Win9x and PNP best of times and found hardware still detects/works fine with it disabled.
Removing the NIC and Sound takes out the possibility that they are causing the issue.
You can enable them one by one if it works out that was causing the issue (which of course is still no guarantee)

It is the hardisk.

First I disabled all the hardware in the bios and reinstalled. Keeps the same. Than I removed the 1TB harddisk and used a 40 GiG PATA and it went trough. The pnp screen only came for about 20 seconds.

So it had to do whit the harddisk. Now I want to see if it is the size or the SATA-PATA adapter. I'll test it whit a 400Gb PATA and a 320 SATA disk.

What I could do, is to clone the installation from the 40 gig disk onto the 1TB.

.... And heck yeah.. it is a Powerful system 😁 even thought about watercooling... Still have a lot of older WC stuff from that time here..

98 has a 128GB limit btw. There are 3rd party patches but I have not tried them.

I know. But that is not the reason. Today i installed W98 on a 400 Gig harddisk. Off course it sees not all the 400 gig while installing. But therfore i Install on a small Partition.

Yeah, the w98 install must be done within the first 2^28 sectors (thanks to LBA28),
and only after applying the LBA28 --> LBA32(?) patch
then you can resize the partition using
non-destructive partition resizer program such as PowerQuest's Partition Magic.

Yes. But i wont resize the win98 partition. I planned to make 3 triple boot along with W2K and Wxp. Using PowerQuest Boot Magic as boot manager, i like that one.

The Partition plan a.t.m. is:
Win98 8GB Primary Fat32
Win2K 8GB Primary NTFS
WXP 20GB Primary NTFS
and the rest as Extended and Fat32
