If ever there was a long discription of a can of worms, this looks like it. I don't say this to slight you in any way; it a description of what I see as a difficult mess to sort out.
start with this:
volume FS Capacity(GB)
sda3 RAW 65.87
sda2 ACER(C) NTFS 43.31
sda4 DATA(D) NTFS 111.43
That tells me there were four partitions and one unpartitioned space when you began.
Partition num: 0, Filesystem type unknown, partition type 0x27
Partition num: 1, Filesystem type unknown, partition type 0x6
Partition num: 3, Filesystem type unknown, partition type 0x7
Partition num: 4, Filesystem type unknown, partition type 0x82
That tells me you have a type 27 (I can't find it anywhere, so it's probably specific to Acer; probably disk diagnostics or some such); type 6 is probably something like fat16 or fat32; type 7 is OS2/NTFS; and type 82 is Linux/Solaris swap. You don't have a Linux type 83 which is Linux native- where Linux would be installed.
I can also see:
Filesystem type unknown, partition type 0xf
(the raw unpartitioned space)
This type 0xf is win95 extended partition type (extended partitions serve as containers for other partitions).
With what you have here, I can't see the actual order of partitions on the disk. I can't tell if there were four primary partitions when you began, and tried to add another. That won't work, because there is room in the MBR for info on four partitions only. There should be, at most, 3 primary partitions, and at least one extended partition, if you want to make partitions for other OSs. The partitions for those other OSs would have to be created inside the extended partition.
Even if you created a Linux swap and Linux type 83 inside sda3, you wouldn't be able to boot Linux, because sda3 represents a fifth partition. And, as I mentioned, the MBR only holds info on 4 partitions.
It seems, on the surface, that your attempt to install Linux went far enough to write grub to the MBR, but the rest of grub (in the linux partition) is out of reach because it's in a forbidden area outside what the MBR has info about.
To sort this out, you would have to boot a liveCD distro such as Knoppix, Kanotix, or some other. When it's up and running, from a terminal, run 'fdisk -l' and write down the information. Fdisk will produce a 'picture' of the disk partition structure. We need to see that structure. How many primary partitions, where is the extended partition, what's inside the extended partition.
In the event it becomes necessary to start deleting partitions in order to re-create them in proper structure, you may be able to save the partitions to be deleted by first making backups to cd/dvd (using the liveCD distro), then build a new partition structure, following by restoring from backup media.
The dd utility can make a bit-by-bit image of the partitions, so that restoring will be an exact bit-by-bit image. I'm not certain though, if dd can write to cd/dvd. Someone else may be able to answer that.
At any rate, get the output of fdisk -l and let's see what can be done to sort this out.
