My laptop (Lenovo Ideapad Y560) running on Windows 7 64-bit stopped booting. These are the messages I receive while trying to boot:

I was able to load the Repair disc Windows 7 64-bit to get to the System Recovery screen but there is no Operating System listed.
I click on Load Drivers and it goes to X:\Windows\system32. Not sure what to select here. It is expecting a file of type
"Setup Information". MUI ??
I click on C: from the drop down menu and I get a message saying "C: is inaccessible and needs to be formatted being it
can be used". I exit that screen.
Ran the Startup Repair many times. No change.
I went to Command Prompt mode (DISKPART) and list volume as mentioned in this thread:
Volume ### Ltr Label Fs Type Size Status Info
------------ --- ---------- ---- --------- ------ ------- -----
Volume 0 E Repair Disc UDF DVD-ROM 165 Mb Healthy
Volume 1 C (No label) RAW Partition 29 GB Healthy
Volume 2 D Lenovo NTFS Partition 29 GB Healthy
Volume 3 (No label) RAW Partition 421 GB Healthy Hidden
Volume 4 Lenovo_Part NTFS Partition 14 GB Healthy Hidden
But the thread above has a step to restore the "bootsector code". But I don't find bootsect.exe in my repair disc. It only
has boot and sources directories and bootmgr.
So I go online & download bootsect.exe, and a bunch of 64 bit drivers from Lenovo site, and burned a new repair disc. I
also included EasyBCD 2.0.2 on it. But for some reason the laptop just wouldn't boot from it. I had made sure that all
executables on the root folder. But it boots only from the original repair disc that doesn't have any drivers or
Is my C: (volume 3, 421 GB) corrupt? It shouldn't show up as RAW or hidden, right? But its status says it is healthy.
I am kind of stuck at this point. Any ideas would be greatly appreciated.

Hi gctex and welcome to the Community,
C: should not be listed as raw. It should be NTSF.
I would boot up into a live linux cd and run a diagnostic on the hard drive and go from there.
Did you resize any partitions before this happened?

How did you solve your problem?
I also have a Lenovo Ideapad Y560 and am having the same problem all of a sudden.
When I check the priority order, it shows:
IDE CDptiarc DVD RW AD-7700H
PCI BEV:MBA v.12,2,5 Slot 0900
What are the IDE fields supposed to contain and what is the problem if they are blank?
I am really confused because I had given mylaptop to be checked at the service centre for keyboard issues, but they did not find any problem and I checked my laptop right after that!
But after 4 days, I am suddenly getting this "Operating system not found" error!

I had this exact problem and am struggling to fix it. Currently I bought a new 64 GB SSD. That seemed to fix the hardware problem. But without the recovery CDs I'm having problems reinstalling the OS

What exactly is the problem installing the OS and what OS were you running?

I have the OneKeyRecovery factory default restore disks. I used them to install Windows 7 64bit to the C drive (SSD). It's only 64 GB so it fills up quickly. I got it working but I feel like something is wrong because now it always runs out of disk space. After installing Windows I tried to recover my files using my Windows backup but it stops halfway through saying I'm out of space. So it seems like before I had more space than now. On a different thread they said to use the Intel Smart response caching system. But to do that I need raid and it seems l ike I don't have that ability on my bios

Solved the problem. I needed to install/run Rapid Drive
So the solutions was:
1) install new SSD as C:
2) install Windows on C:
3) run Rapid Drive to merge C: and D:
