1420350 2016-05-11 20:41:00 Missing operating system

My Son's Asus A53S laptop has just yesterday come up with Missing operating system, I think it has automatically upgraded to windows 10 from seven and is now missing the boot sequence as it must have an Asus partition there for restoring win 7.

And no it was not backed up unfortunately!

So whats the best way to restore it back to win 7 as its his business PC.

Yeah the plugged in usb stick or hdd seems to trip up a few people

1420353 2016-05-12 01:21:00 Hi I have looked in the bios everthing seems to be in order. Removed hdd tried to look from another pc and its telling me I have to reformat drive?

Also tried repair with win 7 disc no go

My other alternative I can restore from the Asus laptop but will lose all files

Is there an alternative?

What are you trying to read the drive from ?

You really need to look at it with partition software to see if theres anything on the drive. Could simply be a messed up boot.

For example if you had something like AOMEI partition Assisant you may see similar to this:

The Second Drive in that Pic is a screwed up W8 due to bad sectors, but it shows all the partitions etc.

"IF" the drive is showing as empty then basically anything you do will be a fresh install anyway, as all the data would be gone, unless you did a data recovery on the drive.

1420356 2016-05-12 04:22:00 Enclosed 640 GB Oh Dear:( ---- you'll need to do a data recovery on the G Drive if you want any data back, for some reason its been wiped by the looks.

What you can try, it may or may not work, is, (mine is the pro version -- cant remember if the std has this option) click on the drive, see is partition recovery option is there, if it is run it.

G: is only 148G , may not be the Win partition ? given H is 640G
Who knows where there data was with that setup.
Thats one piss up of a partitioning right there. As usual on some laptops

Laptop manufacturers sometimes use non standard Win partitioning , in non standard order . And sometimes non standard bootloaders.
All just asking for issues .:badpc:
It could be that a win10 ug just couldnt cope with that drunkard partitioning ? Boot partition seems to be in the middle, rather than 1st

1420358 2016-05-12 05:16:00 I can see the G: which is formatted When I click on it Advanced options Set active partition greyed out! check partition OK do I click this ? I have the Pro version also micky (7329)
1420359 2016-05-12 05:41:00 G: is only 148G , may not be the Win partition ? given H is 640G
G @ 148GB will more than likely be the OS partition, if you look at the Data partition H that's 425GB The F is recovery @ 21GB ( which is about right) and the other smaller partition cant see it fully but may be 4GB so adding up 425+148+21+4 = 598GB which is roughly what a 640GB drive would show.On the far left it says Disk3 596GB = 640GB drive.

Suggest you install something like RECUVA (www.piriform.com) on the working Computer- Point it at the unformatted partition, set it to do a deep scan -- May take several hours (last drive I did took just under 26 Hours) :sleep But that was a 1TB Hard Drive. You'll only be scanning 148GB on one partition. See what it finds.


Some of the manufactures really do have strange partitioning -- HP's are the worst :waughh:
