In most cases of an unbootable system, the user encounters a BSOD (Blue Screen Of Death), black/blue screen with flashing cursor, or a 'startup repair' failure error message. In either of the above outcomes, data saved in Windows 7 based hard drive becomes inaccessible. To access the data in such situations, Windows user needs to restore data from an updated backup. However, if the backup disappoints you and restores incomplete data, then you will need to use an efficient third-party Data Recovery Software to recover lost data. Below is one such scenario that explains Windows 7 unbootability problem in detail.
Suppose you have a dual-boot system with Windows Server 2008 and Windows 7 operating system (on primary partition) installed. You installed some driver updates in Windows Server 2008 and restart your system. However, to your surprise, when you reboot your system, you encounter a black screen with flashing cursor. The black screen appears every time you try to boot your system. Since the system is unable to bypass the black screen, the data saved in both Windows Server 2008 and Windows 7 based partitions becomes inaccessible.
Cause
The above stated problem occurs under following situations:
Corruption in Boot.ini file
Invalid device driver update
File System damage
Resolution
To resolve the above issue and to access data saved in both the partitions, you will need to follow the below steps:
Boot the system in Safe mode and select 'Last Known Good Configuration' option
Try to boot your system using 'Startup Repair' option
Run 'CHKDSK' command to repair the file system
However, if all the three resolutions fail to resolve the issue, then you will need to reinstall the operating system and restore data from an updated backup. However, in case of no backup, you will need to recoup data using commercial Data Recovery utility. Such Data Recovery tools use effective recovery techniques to recoup data after almost all logical data loss scenarios.
Windows Data Recovery is a third-party data recovery software that recovers data from formatted Windows 7, Vista, XP, 2003, and 2000 based hard disks. Supported by almost all file systems (NTFS, NTFS5, FAT12, FAT16, FAT32, and VFAT), the tool is easy to understand and doesn't require any prior technical knowledge.

Boost Your Computer’s Performance with Windows 7 Virus Scanner
Nowadays, computer viruses are getting more and more sophisticated and can enter your computer even if it is equipped with antivirus or antispyware software in a deceitful manner. So you should be very much conscious about the security of your computer data. These viruses can ruin your computer’s memory as a consequence of which, you may face serious issues with your operating system and application software. You can even lose your entire data stored over the hard disk.
Windows 7 has been shipped with immense features, which can take care of your security concerns by scanning and diagnosing the viruses on real time. So there is no need to depend on antivirus software, which offer only limited protection and that’s too after shedding a considerable amount of money.
But you need to be careful about their status on regular basis.
Features
Inbuilt features of Windows 7 like Windows Firewall and Windows Defender play an important role to protect your computer from viruses and other malicious threats. They must be kept well configured and enabled at every moment when you are online. These are equipped with anti-spammer, effective scan engine, Guard, Quarantine, and Scheduler features, so that you can get holistic protection from all offline and online threats. They can scan and remove computer virus instantly from your computer.
Usability
With the above Windows 7 virus scanning tools, you can get good protection from viruses and other malicious software, which harms your privacy and computer’s performance in many ways. These tools monitor your computer on real-time basis, so that you can keep your memory and Windows registry in a sound condition, which will avoid probability of hardware and software conflicts and minimize chances of blue screen error, hard disk crash and sluggish performance.
Limitation
It has been noticed that Windows Firewall delivers only one-way protection. It can check either the incoming or the outgoing traffic at a time. Windows firewall often becomes problematic, when you try to download or install some application software on your computer.
Recommendation
Keep your Windows Defender and Windows Firewall in a well configured state and also ensure they are enabled. To combat with severe infection from computer viruses, you can deploy online scanner tools available on trusted website. For quick resolution, you can call your tech support provider, which can assist in real-time.

Windows 7 Operating System Security
An operating system is always developed keeping in mind the advantages and disadvantages of the microprocessors of that time. The hardware should always be at par with the software and vice versa. I am actually trying to point at the 64 bit implementation of the Windows 7 on Intel Core vPro processors. Windows 7 has gone through a Security Development Life Cycle or SDL in which technical aspects were taken into account. To get assistance on computer security, consult a tech support expert. Let us discuss the outcome and implementation of it as seen in the operating system.
1) Data Execution Prevention or the DEP feature of the OS executes the ED it or the Execute disable bit in Intel Processors against computer viruses that uses the buffer-flow technique for corrupting the computer.
2) Address Space Layout Randomization (ASLR) is another worry factor for those hackers who target specific memory address locations. Imagine that the critical areas of your hard drive where data and other system files reside are being hacked to the level of specific addresses but if the address locations are randomized then no matter where the data resides, it will be difficult for any malicious code to detect it and bring harm to the computer. Cool idea isn't it?
3) Safe Structured Exception Handling. What is that? Well, an exception is a situation which is other than natural and needs to be taken care in a specific manner. This, in programmed structures are done in a specific way so that subroutines are robust enough when due to a virus infection or system file corruption an unwanted situation arise in a computer.
4) Do not forget the Kerberos v5 a protocol for encryption that is used to send passwords over the internet. The question is why should we do so? The answer is that even when you are logging into a website you need to put a password which is again using the internet as the carrier.
5) There are a number of tools which enables us to look after the health of the operating system like the Event Viewer and the UAC (User Account Control) which gives you the required security and at the same time better tools to dive into the changes that went on in the recent past and created the problem you are facing now with the computer.
All said and done, the question still arises as to why do we still get virus infections in our computer? The answer is that no machine in this world is fully perfect and the war between the good and the bad continues no matter whether one wins the temporary game against the other or not. The malicious-code writers are still there. Consult a good technician for total PC maintenance and virus removal. It is not always the branded antivirus software that can give you total security form malicious code. The wireless connectivity between your router and the computer, encrypting your mails, configuring your antivirus cum firewall are some simple ways that actually serves your purpose.
