Partition found table type None, but not using NTFS

First of all, thanks for the great TestDisk utility.

After using a bootable live CD, somehow my netbook won't boot anymore.
Booting linux and viewing the partition table of the disk showed a corrupted partition table.

After having tried various tools and methods to recover the partition table, I stumbled upon TestDisk.

Using TestDisk, with partition table type set to None I am able to find the partitions and even copy some files from these partitions to a backup location (thanks to TestDisk for saving these files so far!)
I can't however write the partition table when using type None. Using type NTFS, TestDisk finds the first (ACER recovery) partition properly, but not my C:-partition. It's found, but without the name, and I can't copy files from it.
TestDisk doesn't provide me with the option to 'Backup BS', as mentioned on the wiki.

So I was hoping you might have a suggestion how to recover my Windows NTFS partition named "ACER".

Attached is the log. On my ACER-partition were some files with raw (ISO) images of USB drives and bootable CDs, so that explains the found partitions Kingston and Debian Inst.

I'd need infos from testdisk analyse, the result after quick search and how your disk is listed in testdisk!

Thanks Fiona, attached are some photos of different results.

I'm not sure what you mean by 'how your disk is listed', I hope the attached files do show the required information.
Two more images are attached in my next post, since the limit is 3.

Your Acer-partition is listed.
Did you try to list your data and from that partition above too?

As far as I've seen, your partition table contains one partition using the complete space.
Your PQService partiton doesn't matters at the moment.
It'll be considered when your acer partition is found correctly.

I have tried listing files for the PQSERVICE and ACER partitions, in different results.
Whenever the name was properly found, I was able to list the files.

In the result you linked to I have also tried listing files on the partition just above the one with the [ACER] label.
The files can't be found on that partition.
(Though on the one with label, they can)

Please let me know, which Acer-Partition lists your data and your PQSERVICE-partitions also.

Sorry if I was unclear at first.

I can list my files on every partition with a proper label (checked for ACER and PQSERVICE).

So that would be PQSERVICE with
- NTFS - Quick Search
- None - Deeper Search

And ACER (the one with the label) on image 5-None-deep-result.jpg, start [784, 3, 52], only with None - Deeper Search

When you choose partition table type None, so you will be not able to write any partition to your partition table.

Due to some issues about your partition geometry I'll have another check!
Might be possible that testdisk finds more
Just repeat your diagnose using another geometry.
Start TestDisk
Confirm through (your affected disk must be selected) until you see the menu Analyse.
Don't confirm at Analyse but Geometry.
Highlight [Heads] and change it to 240.
Don't change anything else and leave the menu at Ok.
Repeat your Diagnose at Analyse.
I'd need infos from Analyse and Quick Search and if partitions not found, from Deeper Search too!

(Before, when mentioning table type NTFS type, I should've mentioned Intel as partition table type.)

Using partition table type Intel, and changing the Heads to 240 in geometry, these are the results.
I still can browse the found PQService partition, but not the other one.
When starting the Quick Search or the Deeper Search I also get a warning
"Warning: the current number of headers per cylinder is 250 but the correct value may be 255. You can use the Geometry menu to change this value. (...)"
